So I apply the 1.5a patch to the Fire Red rom, change the header to MrDS using hxden, open it in Gen III Suite (after updating the pokeroms.ini to the new one provided in the MrDS' rombase) and I'm still getting the \x issue.
So what am I doing wrong?
Edit: So, the first time I open it in Gen III Suite, despite everything having \x next to it, it opens without question. The SECOND time I open it using Gen III Suite (without saving anything the first time) it throws an error at me: (again, I would post a screenshot but I'm not allowed to)
"The game code of this rom is MRDS however its rom id, 0006, tells me that the I should load a section of ini with gamecode BRPE. Logically, if these don't match, I will be trying to load from the wrong offsets. Would you like to continue loading? Click 'yes' if you know that the gamecode should be different since you changed it yourself. Click 'no' to reset the rom id and create a new ini section for this rom."
