Well when the person told me they said look for a file under Script.kom called hellmode. Hell Mode is translated as Champion Mode. I found one called usehellmodebtn, but this is all that's listed.
This is NAGC's btw. KGC has it set to -1(Or 1, I'm not sure). Trying to change it doesn't seem to work(At least for me). I'm really gonna guess that its only possible to change Champion Mode ticket use via the server but I want some confirmation on this. I know it is possible to change Champion Mode by switching files.
NAGC is required to do them in order from Outer Wall of Serdin to Altar of Judgment(Latest dungeon) to obtain the crest. KGC and all the others can be done in any order, but if you start from Outer Wall of Serdin, you halve the next Crest, and if you keep doing them in order, you halve the next one(Silver Land's start being counted after Kerrie Beach, and requires the previous Silver Land Dungeon for the Half Requirements). Not only that, but there is a low chance(About 3%) of you automatically obtaining the Crest at the end of a run.
A friend of mine changed NAGC's files to KGC's and was able to obtain the Wyrm's Maw(Ignis Mountain for the Phillipines) Crest in less than a day due to it dropping.
That's kinda making me think some elements of Champion Mode, and even Expedition Mode(The PVP Boss mode), can be edited through the files.
