hi. i hacked the taito chase hq rom to work with the usa vaus (arkanoid controller). the patch is up on my site here
http://www.angelfire.com/retro/kingmercury
(sorry for ads, its a free site)
this is a standalone patcher because the original rom needs to be copied and ips can't do that and i don't know how to generate the patch using bps or whatever.
works on powerpak and should work on a tsrom cart.
