No.01289 etabeta Developer Jun 16, 2008, 07:58	Same regression (and equivalent backtrace) in jchan.c games. Not sure if it's worth a second report: I guess haze could fix these as well when he fixes galpani3
No.01721 etabeta Developer Jul 20, 2008, 13:44 edited on: Jul 20, 2008, 13:44	I've just submitted a fix for these crashes. Anyway, it's worth to keep an eye on these games after 126u2, since there could be regressions due to the new (and more accurate) graphical emulation from suprnova.c
No.01725 Haze Senior Tester Jul 20, 2008, 15:23	yeah.. they share the code, I didn't care about them too much as they're not likely to do anything useful until the MCUs get decapped (Gals Panic 3 isn't that easy to get hold of.) .. and even then, it looks like actually dumping the MCUs is hard, they're meant to be mask parts based on the part # shown on the PCB, but we see no mask rom
No.01728 etabeta Developer Jul 20, 2008, 16:53	thanks for clearing up the situation. my comment was due to the fact that, after applying the fix for the crash, both galpani3 and jchan graphics have more issues than in 125u4
