Hi Kirk! >I wasn't sure how to make a 2K rom though, rather than >the usual 4. Also I'm not sure about It's ok to submit a 2K or 4K ROM, if only 1K is used and the rest is zeros. > "Use the first 1024/4096 bytes of the cartridge, fill > the rest with 0s, and don't use the 0s as data (or > code, but I don't know what a lot of BRK would be good > for)." That is a *bug* in the description. One obviously can't follow this instruction, since you need the startup vectors. :-) Try this at the top of your source: ORG $F800 ORG $FC00 Now the first 4 pages of the ROM should be zeros and the last 4 should contain the 1024 bytes of your game. That would be a valid 1K entry in a 2K binary.
