Hi, I'm Asura. I'm working on a new PlayStation emulator that I'm calling Tesseract. I'm doubtful it will ever be the best choice for a PS1 emulator. It's more a learning project to understand how emulation works.
Still, I'd like to do something for the community, so on this site I'll document my findings and take notes as I go along. If you'd like to contribute some additional documentation here, or spot any errors you'd like to see corrected, or if you just want to be informed when new content is posted here, you can find me on Twitter.
