No.08969 Kale Developer Sep 26, 2012, 18:39	No idea if it's a bug that happened in particular circumstances or it always happens, needs checking.
No.08970 Kale Developer Sep 26, 2012, 21:40	It happened again here: http://mamedev.emulab.it/kale/fast/files/robokidj2_2.zip It also writes garbage to the ROM, so I don't think it's something that should happen ...
No.08971 Haze Senior Tester Sep 26, 2012, 23:58	could be just a bug in that revision, guess you should check the code changes btw setname is robokidj2 not 2j

No.08993 B2K24 Senior Tester Oct 1, 2012, 07:34	After 3 hours of playing I made it to Act - 16 without any errors or resets using 0.147 X64 official Binary. I know it says save states are not supported, but maybe those and the snaps can be of some help. Really frustrating game to play for long periods of time. When I hit Act - 16 I just decided to shut it off.
No.08996 Kale Developer Oct 2, 2012, 21:33	Save states aren't supported, so it doesn't happen when you try to load it. Additionally, it happened to me with the the robokidj set as well, so it's not a robokidj2 specific issue.
No.08997 B2K24 Senior Tester Oct 2, 2012, 23:50	Since I am so horrible at playing the game and never had more then 2 power-ups at a time, perhaps when 3 or more are active, it possibly increases the chance of rolling this error?
No.08999 hap Developer Oct 3, 2012, 19:47	I suspect it is a BTANB, so I'm setting it to possible. There's a workaround for this issue in MAME now, please don't set it to resolved because of that.
No.13265 Kale Developer Oct 11, 2016, 19:56	Another similar bug happened at stage 10, at the green worm spot. http://mamedev.emulab.it/kale/fast/files/0001_441313800.png I'm prone to think there's something weird going on here ...
