Usually the tiles are store in a raw format, with a graphics ripper you should see something like a big vertical strip with 16 pixels width.

Re: shadow of the beast ST (Mark mc cubbin here)

The problem it's that, when it's accesses without .w it's stored as $00ff8606, if I expand the value to 32bits to have $ffff8606 the bin compare to test the disassembly will fail.

I've no idea how to fix it.

Re: shadow of the beast ST (Mark mc cubbin here)

This version has the labels with a ':' at the end.

About the last question... I need to think how to fix that, maybe tag each label with a size.

Re: shadow of the beast ST (Mark mc cubbin here)

F*ck, I didn't save the project and there are some missing entry points, so the code it's generated with different labels.

If you have changed a lot of code, maybe it's better if you use an editor with regular expression to match a label at the start of a line and replace it with a ':' at the end.

Re: shadow of the beast ST (Mark mc cubbin here)

yeah, the movem it's in a weird format it's in my TODO list, and the cmp you have to include a '#', it looks that I've a bug in my disassembler and in my assembler XD.

Re: shadow of the beast ST (Mark mc cubbin here)

I forgot to include a jmp at the start (and change the org to X - 6), because the entry point it's at line 19002.
