Genesis Plus GX is a Sega / Mega CD, Genesis / Megadrive, Master System, Game Gear and SG-1000 emulator. This is a port of Charles MacDonald's Genesis Plus to the Wii, with a lot of improvements.

Information

see included README.pdf

Installation

SD Card

The SD card should be formatted to FAT (FAT16 or FAT32). If not found, the emulator automatically creates a directory named “/genplus” at the root of your SD card, as well as subdirectories required by the emulator to store miscellaneous files (cheat, save & screenshot files).

By default, the emulator will look for files in the sd:/genplus/roms directory but you can place them anywhere you want, the menu keeping trace of the last accessed directory for each device.

USB Drive

The USB drive should have at least one partition formatted to FAT (FAT16 or FAT32), other file systems (NTFS, EXT2, etc) are not supported. If no SD card is inserted when the emulator starts, it automatically creates a directory named “/genplus” at the root of your USB drive partition, as well as subdirectories required by the emulator to store miscellaneous files (cheat, save & screenshot files).

By default, the emulator will look for files in the usb:/genplus/roms directory but you can place them anywhere you want, the menu keeping trace of the last accessed directory for each device and for each file types.

To use an USB2 drive, you must have IOS58 installed (it should be automatically installed with System Menu 4.3 update). You should also load the emulator through the Homebrew Channel, using the provided meta.xml file and make sure Homebrew Channel is using IOS58 as default IOS. If not, you might need to reinstall Homebrew Channel after having installed IOS58.

DVD

The DVD should be formatted using ISO9660/Joliet (refer to the user manual of your DVD Burning software for more details).

By default, the emulator will look for files at the root of your DVD but you can place them anywhere you want, the menu keeping trace of the last accessed directory for each device and for each file types.

To use DVD on a non-chipped Wii, you should load the emulator through the Homebrew Channel and use the provided meta.xml file, in order to allow full access to the DVD drive.


Mega CD emulation

1) Original BIOS ROM files are required (one for each region): unzip & rename them to bios_CD_U.bin, bios_CD_E.bin, bios_CD_J.bin in /genplus/bios/ directory

2) When using ISO image files, WAV files should be provided as AUDIO track files. You can either load a CUE file pointing to a specific ISO file and containing all the needed information about AUDIO tracks files or directly load the ISO file. In the latter case, the emulator will first look for a .CUE file with the same base name, then if no CUE file is found, it will automatically look for .WAV files respecting one of the following naming format (“XXX” being the .ISO filename and NN being the track number): “XXXNN.wav”, “XXX NN.wav”, “XXXNN. wav”, “XXX – NN.wav” or “XXX_NN.wav”. Please note that compressed audio files (such as .mp3, .mpc, .wma, .ogg, etc) are NOT supported.

3) When using BIN images files, audio tracks are generally stored within the image file. A CUE file is therefore required with all the needed information about audio tracks location. You can either load the CUE file pointing to the specific BIN file or directly load the .BIN file. In the latter case, the emulator will automatically look for a CUE file with the same base name as the BIN file.
