Hi, I helped to find the codes Heinz gave. Looks like those codes Heinz mentioned reference bank C7, which would have to be a mirror of some lower bank because the game in question is only 2 MByte. Indeed the gg code targets the fastrom mirror. This is the true address requested by the CPU on runtim...

ok, snestool change byte $29 to $a9 @7b2e5 in the rom file, ie "and #$10" becomes "lda #$10" in the code listing I gave earlier. The gg code to mimic this would be: $c7b2e5:a9 ($c7b2e5=$7b2e5+$c00000 : hirom, no header) => CB83-8F9A To calculate the right address - without using ...

Well I don't know from where you got the rom (and I don't want to know) but the goodsnes and no-intro db all agree on the same hash for SoM German which is not the same as yours. Anyway I'll show you how to get the gg code by yourself. This is using the german version with the following hash : (md5)...

Hi there,
The wiki page of the Quickdev16developer cartridge describes a debug console.
Does this allow remote code debugging via a serial port ?

As I still hesite between the powerpack and the quickdev16 for homebrew development, this would be a killer feature.

Thk you.

Hi Heinz2001, Patching based on a generic seek and replace method is not always reliable. Indeed I've already come across games where the code pattern of the protection is not listed on the web page you gave earlier. This half broken "feature" would be hard to support for the powerpack des...

Hi there. These new findings are quite exciting. Some protected games do their check during the game, not only at the beginning. PICs don't come with crystal balls, so you'll have to switch manually in that case. One doesn't need a crystal ball ^ ^ AFAIK, a majority of games detect the region on run...
