No.07248 hap Developer Feb 20, 2011, 19:32	Hmm, I looked at it a bit more: none of the blending flags are set (in the priority encoder), and none of the unknown sprite flags are set either. Yeah, it's more likely it's normal behaviour. (setting "possible" flag, it's upto another's opinion to confirm or close this report)

There are ports to Sega Saturn and PlayStation 2, but they are rather weak proof. Check 7:20. Sega Saturn port: http://www.nicovideofire.jp/watch/sm12998674
No.07252 hap Developer Feb 21, 2011, 16:20	PS2 port is weak proof indeed (post-MAME port) Saturn version + your memory: ok, closing this report, thanks =)
