cc65 C compiler is compatible with the console, although there is no development library supported for it. There are a few original TurboGrafx CD games being made such as FX Unit Yuki: The Henshin Engine and a port of Mysterious Song in 2012. SNES / Super Famicom Bung Enterprises released the Game Doctor SF hardware series. It allows users to copy games and run new games on SNES hardware. ROMs can be converted into the Game Doctor SF format and put onto a 3 1/2" floppy. Games as large as twelve megabits can be put on floppy disks formatted to 1.6 megabytes. An alternative device is the Super Flash, by Tototek, which allows multiple games to be burned onto a flash memory chip in a cartridge. This allows games as large as 48 megabits. Apparently the system can program compatibility with C compiler. The run and gun game, Alisha's Adventure, used original Super Famicom development hardware. Neo-Geo MVS, AES, and CD The Neo-Geo Home Cart and Arcade Systems can be tough candidates for homebrew development. Neo-Geo AES and MVS cartridges have two separate boards: one for video, and one for sound. If programming a cartridge for the system were to occur, it would involve replacing the old ROM chips with one's newly programmed ones as the cartridges are in a sense, Arcade boards. NGDevTeam who have released Fast Striker and Gunlord found a workaround with this. What they did was print out their own board, and soldered their own ROM chips into them; this, however, can cause the Universe Bios logo to look corrupted if a custom bios were to be programmed. Programming for the Neo-Geo CD, however is easier than programming for cartridges. The CDs themselves can actually contain both sound and video respectively. Depending on the Megabit count for a game program, load times will vary. A CD game with low Megabit counts will load only one time; whereas a CD game with higher megabit counts could load in between scenes, or rounds. There are now some full games scheduled for release in physical form, such as Neo Xyx. Programmer of the Neo-Geo Universe Bios, Razoola is currently working on a "Skeleton Game Driver" that supports two players. This ROM is meant to remedy the corrupted Universe Bios Screens, as well as work with an unmodified/stock Neo-Geo Multi-Video System (MVS), or Advanced Entertainment System (AES). Razion is an
