You have to strip away the header and the bank info to do so.

GRG :)


This is very interesting news! Would be great if you could just write a really small HOWTO on how you did it and post it here for our NTSC brothers (and future reference). Please :wink:


Ok, all old action replay.crt images
has a header at the start with various info.
Then there is 4 chip infos for each bank.
(4 banks * $2000 = $8000 (32768) bytes)

Use a hex editor of some sort.
From the *.crt image you delete:

0000-0050 ;contains "c64 image bla.bla.. chip ...."
2050-2060 ;contains "chip ...."
4060-4070 ;contains "chip ...."
6070-6080 ;contains "chip ...."

The size of the image should be 32768 bytes when you are done
Save it an flash it to your RR

"oldcarts.zip" which is online on the cpx page (which all of you have read in detail) includes a ton of cart images ready for use.
