Parsing a command line in C is tedious (Family Size VM #5)
Parsing a command line in C is tedious (Family Size VM #5) YouTube video by Damian Yerrick

My #emulator takes a ROM filename on the #CommandLine, among other options. I use the #musl library's #getopt to parse the command in C. It makes me appreciate the libraries that come with newer languages like Python.

My emulator takes a path to a ROM image on the command line, among other options. I use the musl library's getopt_long function to parse the command in C. It makes me appreciate the libraries that come with newer languages like Python.

In December, I set out to write an NES emulator from scratch, working on it an hour a day every day, recording every minute. I've built the CPU, PPU, and a handful of mappers. I added MMC3 without IRQ yesterday, and the end of the session's time lapse shows the first area of Full Quiet.

Perhaps it's getting a bit #gameboy heavy over here, but you've got to have a hobby. Fixed a bug in which I accounted twice for the background scrolling, added some support for ROM and RAM banking, and we have a proper Zelda intro. Link can wake up now. #emudev #odinlang

I have the feeling this will come in handy on more than one occasion. But at the moment i'm just trying to figure out why Link's animation is in hyper mode. I have no clue what could cause that. #gameboy #emudev #odinlang #zelda
