Bugs:
- Original PCB video. Smitdogg (ID 04238)
WIP:
- 0.141u3: Added Cyvern (US). Renamed (cyvern) to (cyvernj).
- 9th February 2011: Smitdogg - We got the rare USA version of Cyvern.
- 3rd July 2008: R. Belmont - The SH-2 DRC successfully got Cyvern past the on-screen POST last night, but that revealed a problem with cycle counting that was making MAME timing and interrupts work poorly at best. I fixed that, but there's now a bug where it crashes trying to resume after handling an interrupt. Never a shortage of fun with this stuff!
- 2nd July 2008: R. Belmont - I've been working on a MAME UDRC frontend for the SH-2 for just under a week now. Last night it finally made it all the way through the suprnova BIOS and into the Cyvern boot code without errors (including handling interrupts). There are still several instructions left to implement before it actually shows something, but so far so good so what, right? This will speed up ST-V (and Saturn in MESS), Kaneko SuperNova, Psikyo SH-2, and CPS3. And SH-2 is a pure subset of SH-4 (aside from different boot vector semantics) so once done this frontend will make a fine starting point for an SH-4 UDRC.
- 0.125u5: David Haywood fixed priorities from start to end in Cyvern (still not perfect).
- 8th June 2008: David Haywood - I took a look back at the Kaneko Supernova driver and fixed up the priorities for Cyvern. The Speed took a bit of a nosedive in the process, but it's a stunning game, and looks even better with proper rendering order.
- 9th September 2007: Mr. Do - Some more instruction cards for more games courtesty of Tormod: Cyvern.
- 0.62: Sylvain Glaize and David Haywood added Cyvern (Japan) (Kaneko 1998).
LEVELS: 5 (must be finished twice)
