Hacking Hacking the Disc Channel

[diddy81]

so i thought i would play with the bmg file today and thanks to the code pune posted i got it working however the disk channel bubble is capped at 20 characters atm
i need to find where the system menu keeps that limit i thought it might be in the brlyt in the balloon.arc but changing that didnt effect it

the 20 character limit is hardcoded into the system menu

this is where it sets the limit. 0x14 is 20. whip up a preloader hack to change that number and you should be good.

li	  %r5, 0x14

just make sure that you have the text buffer for the tooltip balloon set high enough or else youll have a buffer overflow and crash it.

Lol, I can't wait till we have a paragraph pop up when you hover over the disc channel.

Your poll should have been bullets instead of check boxes because now someone can easily select EVERYTHING. :facepalm:

Question - as I get no reply in the actual NeoCorp PoC thread I thought I'd ask here - hopefully someone in the know might be able to help out -

I'm using the NeoCorp combo channel

Looks like it works great for Wii games - but refuses to find any type of Memory Card for GC games - CAN someone help me change settings on the hidden Neogamma channel so that it allows Memory cards? I have got a real GC card which is not read. That would be great too though I would prefer Emulated card - or Wii card....? Anyone?
