The original Chrono Trigger for SNES was a 3MB cartridge, and it has a world map roughly equivalent to that of FFVII. To be honest, the PSX version is a really shoddy port; it's nothing but a glorified emulator (the original SNES ROM can be found in the PSX ISO), there's nasty load times introduced when going to the menu that weren't in the original. The added anime is also pretty shitty, but that's a subjective opinion of mine, I guess other people might like it.
I have a problem with this firmware, anyway. I've downgraded and upgraded up to 3.40 oe without issue, I can run some game demos and .ISO files. However .CSO files won't show. And yes, I'm putting them in the ISO folder in root and browsing the memory card in the XMB, it shows up Metal Slug Anthology (ISO, in \ISO) and a Lumines 2 demo (in \PSP\GAME), but nothing else (.ISO or .CSO) will show. I've tried changing region in recovery and turning on NO-UMD (which helped Metal Slug), no luck in gettting the games to show. I've read through tonnes of stuff, so I'm really not sure... I do have a third party memory stick, and I've formatted it a bunch of times, but no difference. Suggestions?
