Only meshmod can't for now, while the rest like retexturing with muaskinner, notepad py, xmlbcui, & sound editing still the same, but some are different:
*Models' offset are different, despite having a same texture & still use DXT1
*Huds are DXT3 offsets. Recommend to edit Alpha Channel for transparent BG
*Power Icons becomes very easy on offset. Still uses Alpha Channel & DXT3
*Sounds format are .pak > inside .pak are .fsb > inside .fsb are .mp3. Seems very easy since there's some programs like fsb extractor exist
For 2nd patch, other than just confirmed Xbox 360 DLC exclusives, we don't know if PSP exclusives are also included as well or as unused bonus again like in Wii ver., or possibly for Wave 3 patch. Who know?
BTW, isn't Xbox 360 slots only maxes 34?
