Hi carrion,
You have to set the char generator address in reg $ff13 bits 2-7 and clear bit 2 in reg $ff12. If you want your charset at $2000 try something like this: lda$ff13; and#3; ora#$20; sta$ff13; lda$ff12; and#$fb; sta$ff12 (I hope this is not f*cked up). I suggest you to get SVS' excellent xls about plus/4 memory mapping and other things. It's very handy.
