[Other✓] Help with making poketcg

Cataclyptic said:

I'm just a simple guy trying to make a simple hack of the pokemon TCG game, but for some reason I can't. My problem is that every time I try to edit anything in the SRC folder, it fails to create the rom. And for whatever reason, this ONLY applies to poketcg- I did the same things basically in pokered and made a Fire Dragon Charmander with Solarbeam as its starting move without issues. But for poketcg, nothing works- card data, card names, even changing cards in decklists.

This is the error that crops up:

rgbasm -h -i src/ -L -Weverything -o src/main.o src/main.asm
rgblink -p 0xff -m poketcg.map -n poketcg.sym -l src/layout.link -o poketcg.gbc src/main.o src/gfx.o src/text.o src/audio.o src/wram.o src/hram.o
rgbfix -cjsv -k 01 -l 0x33 -m 0x1b -p 0xff -r 03 -t POKECARD -i AXQE poketcg.gbc
poketcg.gbc: FAILED
sha1sum: WARNING: 1 computed checksum did NOT match
make: *** [Makefile:46: compare] Error 1

Consequently, if I revert any changes I make, the following happens and the rom is actually made:

rgbasm -h -i src/ -L -Weverything -o src/main.o src/main.asm
rgblink -p 0xff -m poketcg.map -n poketcg.sym -l src/layout.link -o poketcg.gbc src/main.o src/gfx.o src/text.o src/audio.o src/wram.o src/hram.o
rgbfix -cjsv -k 01 -l 0x33 -m 0x1b -p 0xff -r 03 -t POKECARD -i AXQE poketcg.gbc
poketcg.gbc: OK

I've bolded the differences between the two scenarios. Does anyone know what this code implies? The only thing I can imagine is that my new changes don't match up with some other internal data structure, but for the life of me I can't find that hypothetical second structure. Been at this for a week but these things just aren't my area of expertise. Please help, thanks in advance.

That error is not an error per se, but a huge warning.
When you run make inside poketcg's folder, a ROM is built.
After that, its SHA-1 is compared with the SHA-1 of a certified copy of the game.
This SHA-1 is "0f8670a583255cff3e5b7ca71b5d7454d928fc48" and it represents a copy of the American release of the game.

When you make a change in poketcg, any change, even a small one, you have to build a new ROM.
This new ROM will not match the official game's ROM.
As such, when the check for the game's SHA-1 happens, you're told that it doesn't match, and that's just how it is. It will never match. A ROM should still have been built though.

So in essence, it's just a harmless warning that you can ignore.
