View File MuchimeX MuchimeX: Multi Chinese Machine Emulator for Xbox User Guide: WHAT IS THIS? ------------ MuchimeX tries to emulate a lot of machines that use a SPG2xx processor (manufactured by Sunplus) with the u'nSP instruction set. This includes several consoles like JungleTac's Sport Vii, a lot of Jakks Pacific TV Plug 'n Play videogames, and lots of other electronic devices. Furthermore, there are other consoles like the Vtech V.smile that use this same processor. Currently this emulator doesn't support their games, but in the future it will probably do it. The emulation is almost perfect and full-speed, except in the sound. The sound is not emulated, because the original PC emulator has not emulated the sound neither. WHAT DOES IT EMULATE? -------------------- It is really difficult to find roms/bios dumps for this kind of devices, but at the moment I have managed to test it with success, wiith all these systems/bios/roms: * Sport Vii / Chintendo Vii: All the internal games work, mainly controlled with the HandyBar/Viimote (read the "Controls" and the "Viimote" sections for more information to play these games). * Sport Vii / Chintendo VII cartridges: I have tested the VC_1 and VC_2 (named "7 in 1" and "10 in 1"), with success. The VC_3 cartridge probably works too, but I have not been able to find a dump of it. Please, let me know if you managed to test it. * Jakks Pacific plug 'n play games: I have tested if with the games Batman and Wall-e, with success. Other games like the Winnie the Pooh one, must work too. And a lot of other Jakks Pacific games should work with a few adds/changes in the emulator. If you find more dumps and they don't work, let me know and I will try to patch the emulator to support them. * As a final surprise, there are a few V.smile games that already load (like the Cinderella and the Ariel ones) but they are still not playable because the controls are still not emulated. But you can load them and see the title screen, as a proof that we are really close to achieve a partial emulation of the Vtech V.smile console. On the other hand, games that use other devices like the VMotion or the V.smile CD, will not work yet, because these devices are not emulated in this emulator yet. * Besides, there are a lot of 16-bit chinese cheap consoles with hundreds of internal games that use this same Sunplus processor, so if we manage to find a dump of their bios/roms, they will probable work in this emulator too (maybe a little patch will be needed, some kind of "2 minutes fix"). WHY CAN'T I FIND THE ROMS? ------------------------- If you search for ROMS, you will probably find only 2: Chintendo VC_1 and VC_2 (or "10 in 1" and "7 in 1"), because those are "roms" (cartridges). The rest of the games are internal of these consoles, so you must search for the keyword "BIOS", not "roms". For example, the "Batman" and "Wall-e" games are the BIOS of these Plug 'n Play consoles. Also, the keyword "dump" can be usefull to find these kind of roms/bios. Controls: The button mapping is extremely easy: D-pad: D-pad A-button: A-button B-button: B-button X-button: C-button Start button: Menu button The BACK button displays the Viimote configuration options, and START+BACK will exit from the game/emulator.

View File MessoXtras MessoXTras is a port of the MESS emulator for Xbox. With MessoXtras, we can finally emulate lots of new systems that we didn't have in Xbox (both consoles and computers). This first release supports 25 systems, but we can add more systems if we want. If you want to help, please contact with HCF. User Guide: HOW TO RUN IT ------------- The emulator works easily: simply launch the "default.xbe" and select the desired console/computer that you want to emulate. After that, you will see all the games for that system, and you can select the one that you want to play. If the emulator displays a message telling "press OK", simply move to left and right the left analog stick, and the game will begin. In the list of systems, you will see that some of them are green, and other systems are yellow. Yellow systems usually need a keyboard to play many games (you can use the Virtual Keyboard if you don't have a real keyboard plugged on your Xbox). Green systems should be easily controlled with a joypad. DIRECTORIES: WHERE TO PLACE THE ROMS? ------------------------------------- You must not change the directory structure, and you only need to know that there is an important folder named "roms". Inside of that folder, there is a subfolder for each system. For example, "roms/scv" is the folder for the "Super Cassette Vision", and "roms/cdimono1" is the folder for the Philips CDi. Do not change the names of these folders! Those subfolders inside "roms" contain both the BIOS files of the systems and the ROMS (games). So, if you have a game for the "Super Cassette Vision", you have to copy it in the "roms/scv" path (more subdirectories are not supported). Controls: ESS have some "Generic" controls (valid for all the systems) and also some "specific" controls for each system. You can configure them in the Main menu, but we have created good configurations for almost all the supported consoles and computers. In almost all the systems, you will be able to control the games with the left analog stick and with the dpad. The main buttons that you will use to start a game or for "action" are the A BUTTON or the WHITE BUTTON in almost all the supported systems, and BLACK button to select game modes. Anyways, the "README-SYSTEMS-DETAILED.TXT" file will have information about the way to use each system. Some special controls that work in almost all the systems: * Left analog stick and dpad: Move * A button: In many systems, it is Start or Action * WHITE button: In many systems, it is Start or Action * BLACK button: In many systems, it is the "Select" button * START button: Main menu * BACK button: Cancel or Exit (exit from a menu, or exit from the emulator) * Left and Rigth triggers simmultaneously: Fast forward (boosts the emulation; it is useful to improve the loading times!) * Press Left analog stick: Load State (read SAVESTATES section for more info) * Press Right analog stick: Save state (read SAVESTATES section for more info) * Move right analog stick: Opens the Virtual Keyboard (read the VIRTUAL KEYBOARD section for more info) * Y button: It toggles the keyboard emulation mode (usually you will not need to do this). * Left trigger: In systems with a keyboard, it is ENTER. * Right trigger: In systems with a keyboard, it is SPACE. FAQ: FAQ --- Q: Can you add more systems? A: Of course. Adding more systems is easy... but learning how to use them can be a long task. If you are interested in adding a new system to MessoXtras and want to help, contact HCF. We will need anyone to learn how that system works, mainly if it is a computer and it needs some commands to be typed to load the games. Q: Why didn't you add support to [ANY SYSTEM THAT IS ALREADY EMULATED IN XBOX]? A: It is really easy to add support to Atari 2600, Gameboy, Sega Master System... Madmab and I tried to do it, but we saw that the emulation in Mess is a bit worse than in the standalone emulators. So, we think that adding already supported systems will only add confusion. Anyways, we are open to add any system if the emulation in Mess has any big advantage over the standalone existing emulators (we don't have found this case yet). Q: The controls (for example the Start button to open the Main Menu) sometimes don't work! A: You have probably pressed the Y button, that toggles the keyboard emulation mode. When you do it, some of the main commands don't work. Press Y button again to go back to the main emulation mode. Q: How does the "Philips CDi" emulation work? A: Surprisingly, it runs at very good speed. At first it worked like a snail, but we did a very effective optimization and now it runs at full speed in Xbox. Some games don't work because some video modules of the CDi are not emulated, but a lot of the most famous games run very well. Q: How can I build valid CDi roms? A: MessoXtras v0.5 supports CDi games in the old CHD format that was used in MESS 0.140. If you have CHD files for MESS, they are probably in the NEW CHD format. in the emulator there is a folder "chd_revert" with an script developed by Madmab, to convert files from the new CHD format to the old one, that is supported in MessoXtras. Q: Parts of the top, bottom, left or right ofthe screen are cut off. A: You can adjust the screen size by pressing Start button to bring up the menu. Then select "Slider Controls". Decrease "Screen Vert Stretch" to affect top/bottom and "Screen Horiz Stretch" for right/left. Screenshots: Credits: Millions of thanks to Madmab for his HUGE help in this project. Also many thanks to the rest of developers that helped with their ideas and support! This project came to life due to the awesome development community under the Xbox scene Submitter Dempsey_86 Submitted 07/11/23 Category Emulators

View File MADrigalX MADrigalX makes possible to play a lot of the "game and watch" handheld simulators developed by MADrigal... in your original Xbox! It is a standalone emulator based on the "game and watch" Libretro core and the work of Andre Leiradella. User Guide: Currently, 59 games are supported (54 of them are already playable at full speed!). You don't need to search for "roms", as the games are already included in the emulator. Controls: Each game has different controls, because each machine has different buttons. If you keep pressed the START button, you will see a help window with the key mapping for the game that you are playing to. In a lot of games, the LEFT and RIGHT TRIGGERS are mapped to the "Game A" and "Game B" buttons. So, to start playing you should press the LEFT trigger (easy game) or the RIGHT trigger (difficult game). A few games have different controls though, and you can always see them pressing START. Besides, if you press BACK you will toggle the ZOOM mode, making the screen larger. Please, be informed that zoom mode is experimental. If you simmultaneously press START+BACK, you will exit from the game. Known issues: * There are a few games that are still not playable: Chicky Woggy, Crazy Chewy, Donkey Angler and Pac Man. * The "zoom" functionality is still working bad in a few games. * The coconut doesn't work well in the "Donkey Kong Jr (Panorama version)". This is not important because you can play the Coleco version, that is basically the same and works well * A few games rarely crash when booting. If this happens, please re-launch the emulator and run the game again. These issues will hopefull been fixed in later updates. Screenshots: Credits: Big thanks to Luca "MADrigal" Antignano for developing these awesome simulators and giving permission to make this possible, and also for his huge support with the rom list interface. Besides, big thanks to Andre Leiradella (twitter handle: @leiradel) for his incredible work converting those simulators to Lua and creating the libretro core to run them. Also big thanks to the Libretro team for caring about generic emulation for everybody! Submitter Dempsey_86 Submitted 07/11/23 Category Emulators

View File Handheld DreamX Handheld DreamX emulates a lot of old handheld machines from Coleco, Bandai, Tomy, Epoch... plus some vintage electronic games like "MB Simon". Controls: Controls are different for each game, and could be redefined in the second option of the main menu (press Start to get this menu). But usually, games start pressing the WHITE button or the A button. In a few cases like the Pacman games, we should press Left or Up to start the game. The normal controls include the 4 directions Up-Down-Left-Right and sometimes one or two buttons (usually A and B). In some games (marked in yellow color) a keyboard is recommended to be able to play. Pressing BACK the emulator will prompt you if you want to finish the game. Press A to confirm or BACK again to cancel. Several games have an option in the main menu ("Machine configuration") where you can set different difficulty levels or kinds of gameplay. Finally, the emulator supports a simple feature to save state. To save state you must press the RIGHT THUMBSTICK (and A button to cofirm, or BACK to cancel), and to load state you must press the LEFT THUMBSTICK (and again, A button to confirm). This is useful because some handheld machines begin the game in a very slow speed (and sometimes it is boring if you are an expert in that game). Saving a state in the moment that the game becomes interesting, makes possible to skip this initial stage.
