Hi All, If this thread's title sounds familiar... it's because it is similar to the one on AssemblerGames. That forum's future doesn't look... uh, too bright. Although I don't really want to commit time on PS2 stuff these days, I would like to share my knowledge so that this becomes a platform that is easier to work with. Link to the article: https://sites.google.com/view/ysai187/home/projects/initializing-the-ps2psx I realize that "initializing" is a very broad topic and perhaps I have put too much information one place. The thread on AssemblerGames had the topic split across multiple posts in that same thread, but I copied them into one webpage. I've (finally) added code from XFMCB, to show how the PSX needs to be configured, to operate in PS2 mode. That means, the PS2 half of the CD/DVD drive is usable, the QUIT GAME button works and the EE RAM capacity is switched to 32MB. Unfortunately, my consoles are all disconnected and packed up, so I did not test this. Since having a broken example might not be great for learning, I have retained the link to the previous bundle on my website. Feel free to discuss and give comments!
