TSV recording doesn't work with 8 bit color.

[dulsi]

The rawFrameBuffer is all 0 in 8 bit color. I coded up a fix in my fork of your simulator. I don't think you can pull it directly but here is a link:

It wouldn't be hard to copy the code into your codebase if you want.

Hey wow, someone is using the crappy code I write?! Didn't think this would happen :D - if you have a fix, just send it to me!
Edit: looking at the code right now of your fix

Just a word of caution: I haven't tested 8bit mode in quite a while; all my projects use 16bit by now, so I suspect lots of broken code like that around all corners (e.g. the texture blitting).

May I ask, why do you use 8bit?

[dulsi]

I was targeting the tinyscreen video game kit not the tinyarcade. I went with 8bit simply to use less space.

I probably should mention two other changes in my version of your simulator.

This draws G and H on the buttons so it is obvious what keys to use (or at least a little more obvious):

This is a script I use under linux to compile projects with the simulator. It avoids having to create the wrappers like you do although it needs bash and other unix commands to work:
