Strangely, no$ 2.6a can't emulate this but its previous version 2.6 can.
If your computer can't run deseume, try no$2.6
Actually, I already mentioned that. I've only had the freezing issue on 2.6a, not 2.6, so you proably were using 2.6a. Try 2.6 instead.
Anyway, updated save codes. (I haven't tested these yet, but these codes MIGHT work for 2.6a as well.)
Black 2
White 2
Edit - All the other AR code did was correct the saving issues that gave out the blue screen of death when the rom loaded. It didn't change anything else other then enabling saving.
Edit 2 - Most rom/emulator sites will only have copies of no$ 2.6a. If your having trouble finding a copy of 2.6, check zophar's domain.
