MAME Info:

0.37b9 [David Haywood, Aaron Giles]


- tfrceac & clones: Some sound flaws. Ace (ID 03963)


- 29th December 2007: Guru - Thunder Force AC will need a trojan to dump the EPM5032 protection chip so I can't do anything with it yet until the particular DEV works on it and/or sends me the required info. I'm told it's not required anyway so this would only be done for completeness.

- 21st December 2007: Guru - A huge box arrived today. That 19.75kg box looks mighty impressive, although I'm not sure that all of it is going to be useful. Some could be alt. versions but most don't work so I'll need to dump all of these before I can tell exactly what they are. It contains Thunder Force AC (Sega 1990, original with 317-0172!) and others. Thanks to Tingoes for sending these out.

- 0.37b14: Changed description of clone 'ThunderForce AC (Bootleg)' to 'ThunderForce AC (bootleg)'.

- 0.37b9: David Haywood and Aaron Giles added ThunderForce AC (Sega / Technosoft 1990) and clones (Japan) and (Bootleg).

- 27th September 2000: David Haywood sent in another Sega C2 driver update with Thunder Force AC bootleg working.
