Anyone here playing PS1 games on PS2 slim? That's working for me. I also have an old school Game Genie disc for PS1 that still works, as does the PS1 memory cards. That was a surprise.
I wish there was a good way to launch pirated PS1 games on PS2.
The "emulators" people have put out are jank and you need a modchip to run PS1 games. She said while having a room full of devices that can emulate the PS1.
PS1 on PS2 tip: PS1 games can't read a PS2 memory card, but PS1 saves are perfectly safe to be copied to and from PS2 cards. Considering how much bigger the PS2 memory cards are it's a good way to store PS1 saves, especially for games with multi-block saves like RPGs and RPG Maker. Might be able to do this with a hard drive too, but slims don't support hard drives.
I don't know if there's a way to hack a DexDrive to run on a PS2, but if you have Free McBoot installed you should be able to copy the memcard saves to a USB drive.
I bought an HDMI to RCA converter, hooked my Computer on a CRT screen. That was an amazing experience, no filter I ever saw matched the quality for old games, it's no meme guys. The pixelated faces in Streets of Rage 2 menu looked more like a regular painting, the rocks in Sonic 3 looked it could pop out of the screen, menus on ps1 were bright and rounded.
Totally recommended! Get some bucks and invest in the HDMI/RCA + CRT TV combo.
I would if I had the money for a GOOD CRT, the room, and of course there's the fact that they eat electricity. yee64 on retroarch is actually my favorite filter and simulates the last CRT I had (some Sylvania joint with S-Video) pretty well.
Speaking of disc images, I'm converting most of mine to Mame's CHD format. It's supported by most RetroArch cores.
It allows Mixed Mode like bin/cue but only needs a single file and it has basic compression (saves a lot of space when there's a lot of zero padding).
Some tips:
Retroarch supports .pbp, but not the official .pbps you can get from something like nps off Sony's servers. Doesn't seem to support multidisc pbp very well. PPSSPP supports .cso but PPSSPP in RA does NOT support this.
You can trim GBA, DS, and 3DS ROMs to save room. I can't get Retroarch to work that well with the .3DS files I have but Citra plays them. Does it play them well? Not on my machine, and I should pick up a 3DS + flashcart sometime along the way. (I prefer flashcarts.)
CHD works for most games.
If you really want to squeeze everything you can, Mednafen supports ISO+OGG and so does Genesis Plus GX. Mednafen supports this for Saturn games, even! However my Saturn binaries are in .chd format because Mednafen Saturn won't run very well on my tablet and whatever Yabause derivative I'm using supports it.
.chd works for nearly all formats. FM Towns on MAME supports it. I wish I knew how to get FM Towns in Retroarch MAME working for dem filters.
Lastly, DOSBox supports iso+mp3.
