If you want to mod actual original PlayStation, we want you here. We need you here. If you want to mod PSP/Android/iOS, we neither want nor need you here unless you have a profound knowledge of the hardware and can work within their heinous limitations. Around here, PlayStation is God, and all other releases are steaming piles of dung that nobody will touch or clean up. WotL = no knowledge, no experience, no intelligence, just using tools from a bygone era nobody will bother to update, and few will use.
Note also: I don't say this as an explicit slight against WotL, just that nobody with any intelligence, modicum of common sense, or ambition sticks to WotL, with the exception of BlueVII's stubbornness. If you can't operate on an assembly level, please don't work on WotL. If you can operate on an assembly level, please work on PlayStation, but I'll still be happy if you work on WotL.
