Chunithm Amazon: Increase max credits to 254

[esterTion]

This is a weird patch

I actually tried 255 (0xFF), and the credit counter rolled back to 0 without stopping, which is somehow extremely funny to me

[esterTion]

so i tried a hacky free play, basiclly change sub to add in credit consume function weirdly when i noped the sub op, the game just crashes not sure if continue add the "254 credits" patch, this new free play patch will exceed the limit anyway. "inserting a coin" will reset it to the limit, but i didn't try if it will roll back to 0 after 255

experiemented with actual Free Play for a while. turns out in actual Free Play, paid tickets are gone. later someone reminded me i can just use or instead of add this way i don't need to worry about overflowing

Alright, seems good
