Good to know. I wondered about storing the value somewhere when the loader would pointto that address, then restore it the loading has finished just before the final JMP. But I said, mine is simply wandering among thoughts

Try it! It will run, but the changed value in $07FC will break the Day 1 depacking, that's what you have to test ;)

Oh, hence: if I don't use -h and -l options, novamaker.exe uses both covering the memory inbetween too; if I wanna add something mine to the code, I can edit both of them, then use the former the latter or both in the new shape I've given to them, adding e.g. new colors, setting a different graphic format and so on. The two files are respectively the samein the /daley_thompson_fire folder, called 00 header.prg and 01 prg.prg. My suggestion is to put them in a folder apart, maybe with their .asm sources too ready to be modified and compiled, in order to clearly offer them to any user for further handling.
The unbootable option should produce pure halfwaved data with no FOUND, initial header and so on, just halfwaved compressed data. You can use it for, e.g., multiload games.
Great stuff indeed, hafta say :)
