Hangs with a frozen window, doesn't respond to any signal other than SIGKILL #25

I'm on Void Linux, kernel 6.6.25_1 with GCC 13.2.0 and SDL2 2.30.1

I'm not sure what I'm doing wrong. It builds, I get lots of compiler warnings but no errors.

It also requests way too small a buffer causing PipeWire to use a excessive amount of CPU, I tried adjusting audio_page_size but the emulator just brings up a window with the "contents" of what was behind the screen when the window comes up and the emulator just uses a lot of CPU and seemingly does nothing.

All I get on the terminal is this:

$ ./nuked-sc55 
Base path is: ./nuked-sc55
Audio Requested: F=S16LSB, C=2, R=66207, B=1024

Are these ROMs bad?

SHA-256? yes these are good ROMs. The emulation is pretty CPU heavy, mind you.

The one thing I see missing in the terminal window, is what midi channel is being used.

I don't actually see any usable MIDI device show up in ALSA so I suppose it's locking up as it's trying to get the MIDI part setup but I don't know how to use gdb to breakpoint it to really see if that's the case.

Okay, I was dumb and didn't notice this was building a additional file that needed to exist back.data and having that in the working directory makes this work, sorry for the confusion...

The instructions should probably point out "back.data" needs to exist in the working directory of the emulator; there's no error messages if that file is missing.
