0.100u2 [David Haywood]
0.37b9 [David Haywood, Aaron Giles]
TODO :
- Puyo Puyo ends up with a black screen after doing memory tests Battery-backed RAM needs to be figured out.
NOTES :
- Sega's C2 was used between 1989 and 1994, the hardware being very similar to that used by the Sega MegaDrive/Genesis Home Console Sega produced around the same time.
- Eng indicates game is in the English Language, Most Likely a European / US Romset. Jpn indicates the game plays in Japanese and is therefore likely a Japanes Romset.
- Bloxeed doesn't Read from the Protection Chip at all; all of the other games do. Currently the protection chip is mostly understood, and needs a table of 256 4-bit values for each game. In all cases except for Poto Poto and Puyo Puyo 2, the table is embedded in the code. Workarounds for the other 2 cases are provided.
- I'm assuming System-C was the Board without the uPD7759 chip and System-C2 was the version of the board with it, this could be completely wrong but it doesn't really matter anyway.
