I'm trying to get a Basic program running from cartridge because, why not?
So, I'm trying to replicate what the rom of the spanish driving test does, which is to copy the program to 0x1E00 and then jump to the basic RUN command at 0x85A5.
The loader code is this:
Code: Select all
CLRA
LDA #$5B
STA >$001B
STA >$001F
LDX #$C020
LDY #$1E00
BSR $C016
JMP $85A5
RTS
LDA ,X+
STA ,Y+
CMPX #$FEFF
BNE $C016
RTS

So I'm not exactly sure what did I miss. Any ideas?
Cheers,
Rob
