info

0.71u1 [David Haywood]

WIP:

0.94u5: Removed cpu1 roms ($300000/1). The Game instruction rom will now copied to 0x300000 - 0x310000 (odd/even bytes equal).
0.81u7: Barry Rodewald and GreyRogue updated the MegaPlay driver, which makes Sonic The Hedgehog, Golden Axe 2 and Tecmo World Cup fully playable. Megaplay still has a few issues (continue without extra coins etc.).
0.81u5: Barry Rodewald improved Megaplay, allowing it to pass more checks.
0.73: Added cpu1 roms ($300000/1) and fixed input and dipswitches.
0.72u2: Added 2nd Z80 (3579540 Hz) CPU. Added dipswitches 'Coin slot 1/2', 'Initial Players' and 'Difficulty'.
0.71u1: Added Sonic the Hedgehog (Mega Play) (Sega 1993). The driver doesn't boot. David Haywood improved Genesis emulation a bit in preparation for MegaTech / MegaPlay, sound code based on MESS.

- TRIVIA -

Released 2 years after the original, this version can be considered as a reduced version :

* Stages : Green hill -> Spring year -> Starlight -> Scrap brain (1,2) -> Final zone.

* You have a limited amount of time per level (usually pretty tight, 1 minute is the easy setting for the first level, 35 seconds seems to be the hardest).

* Extra life boxes do nothing.

* Jumping into the special stage ring does nothing (no special stages).

* When you finish it sonic seems to have the 'you didn't get any emeralds' look despite there being no emeralds due to the lack of special stages.
