IIDX 31 010: increase mdb buffer for omni #369
Conversation

Dunno why it end up here, but as author here's some more information: Theoretically this dynamic alloc patch for music_data.bin should works perfectly up to ~7 MB (by changing two 00 00 60 00 in the offsets to greater value). However when exceeding 7 MB the game will starting to lack some text display, and the larger mdb file is, the less text game displays (although it doesn't affect actual game play). What I assume is that there's still static allocated buffer(s) related to music_data.bin which overflows and overlapping the font buffer, it'd nice if someone could figure out how to reroute this issue. |

Well done, it's quite a fancy patch. We shall see about the 7 MB problem.
