Hello. For those who don't know, I have been working on an open-source port of Sonic 1 for Sega/Mega-CD, which I released at the SonicGamesDimension forums. I thought it could be a nice input, mostly because of the easiness SegaCD games have to be tested on hardware, the extra space, and all it's other nice features. It took me two weeks to do it, and I think it's pretty stable as-is. Works with all regions, and it has been tested on a PAL Mega-CD, where it works fine. Features: Full support for all regions. Supports BRAM, to save the games. This port is based on MarkeyJester's two-eight project. Chunks are 128x128-sized. Little bugfixes to the original engine. To Do: Implement PCM driver Implement FMV video system Support for "Transfer Cable" Download: Revised Source Code: http://www.mediafire.com/download/hx30cpdxc8zlp2c/Sonic1_SegaCD_v2a.rar ISO/CUE files (For USA region): http://trox.binary-division.com/public/S1CD_ISO.rar MP3 files: http://trox.binary-division.com/public/S1CD_MP3.rar SonED2 Project files (Place them on the "Game" folder): http://trox.binary-division.com/public/SonED2_CDProj.rar Credits: HCKTROX - Main author.

Special thanks: HPZMan: (VERY special thanks) Info. provider, help, and others. ChillyWilly: Who helped me to sort out most of mine bugs. SoulessSentinel: SegaCD's template. TristanSeifert: Hardware's notes, misc help. How to use: Before using it, you'll need to compile the game first... Go to source code's root folder -> Game -> BuildAllFiles.BAT That will compile the files required for the disc image Go to BuildISO.bat and you'll get your ISO ready and working. And remember: Every bug you find, don't be afraid to notify me. Thanks!
