6502 *=

I added the entry point instruction to the 6502 screensaver. It allows you to load code at any place in memory.

jmp $1000
*=$1000
lda #5
sta $603

The code above will start at the default address $600 and will immediately jump to address $1000 where the rest of the program is stored.

The funny screen shot above is from Stefan's Santa Claus demo (I know I'm a month late). It uses the entry point instruction to store the bitmaps in convenient locations.
