I *think* I solved my issues by flashing the firmware into the cart again. Seems it got corrupted somehow during the first time updating from 0.17 to 0.20.
EDIT: It looks like any time I write games to the flash it corrupts the firmware and it goes back to being all garbled and crashing again...
I got a Superchis cart just the other day for my (recently bought from a con) DS Lite but I'm having a lot of trouble with it.
It only works correctly sometimes. The other times the menu entries are all garbled and the system eventually hangs (or it starts already not working at all). I can't...
Could be interesting if eventually a mode is made for the brand new VB emu to make it work properly without the silly, expensive and region-restricted-sales goggles.
Besides just the RetroAchievements stuff, would it be possible to implement some form of sharp bilinear filtering (so we can take advantage of as much screen real estate as possible without compromising with uneven pixels or a soft image)?
