Please at least roughly follow PPSSPP's general code style throughout. You're close, but we write for( as for (, and ) and { are separated by a space (last part of the line).

This if chain would be better written as a switch.

Really still want to ERROR_LOG these? Doesn't seem like errors to me, more like the normal execution path.

Would be better to flip the logic of the if and early-out, instead of indenting the entire function.

This stack dumping should surely not occur on every call. Comment out or something.

For good reason, dynamic stack allocation is not a good idea.

Hm, you're right, I supposed I should not be too trusty with snprintf's return value being always

Much, much better! Hm, I think the debug logging should maybe be VERBOSE, but I'll go ahead and merge and possibly adjust after. |
