Atari Development

Where old Atari systems get new love!

Delta programming is almost there.

I basically told my program that there was a ROM already loaded (but it’s all $FF) and ran the diff (cool way to see big blocks of $FF data in ROM’s).

The output is formatted as follows: BANK, BLOCK_NUMBER,  ADDRESS, NUMBLOCKS, BANKSWITCH_FLAG (SWITCH means do the bank switch).

Test output from the control software on OSX…
