I just bricked my ds1 by accident, it looks like it has a pic programming port inside it.. I have ordered a knockoff $20 Chinese pic programmer. While I don’t have the 1.30 firmware I used to have I can at least try to dump the both program and dump the ROM back again, if everything else fails maybe someone that has a newer firmware can dump it if it works.
The latest firmware version I have on hex file is 1.25, seems like i forgot to save newer ones..
