LouisB Posted November 20, 2022 Share Posted November 20, 2022 (edited) Hello, I’m attempting to create / re-create a VIC-20 cartridge of the game “Sky Blazer” by Broderbund. I have two working CRT files (confirmed working by loading them into Vice, attaching the 8KB Images at $6000 and $A000 respectively.) I had some 16K ROM Cartridge PCB’s made using the Eagle files from this thread and burned a 27128 with the CRT files concatenated together. I also removed the first two header bytes from each CRT which appear to be an address header. I tried with $6000 first then $A000, and the other way around and nothing loads up when I power on, I’m assuming it will auto-boot? Anyone have advice on how to test if the cartridge is loaded into memory? Thanks p.s. I'm pretty sure the default jumpers on the card (blocks 3 & 5) line up with $6000 & $A000 EDIT: And I just realized in my rush to make this last night, I forgot to add the .1Uf capacitor, I'll solder that on and re-test! crt.zip Edited November 20, 2022 by LouisB Quote Link to comment Share on other sites More sharing options...
