Problems with 3.71 m33 firmware

MachineAres · 08-29-2008, 01:51 AM

I guess I'm new here, but I've been visiting the site and using custom firmwares and stuff for a few years now.

This is really weird because when i was in the 3.50-3.52 firmwares, all my ISOs and most of the homebrews would run just fine, no matter what. I upgraded about a month ago to 3.71 so I could play multi-disc PS1 games on my PSP, and I never noticed any problems until now, when I went to put a bunch of the ISOs I used to play back onto my stick. These are all ISOs, too, not CSOs or anything.

Now when I go to boot some of these old games that used to work just fine, it gives me a "game could not be started" message and it has since corrupted a few of my homebrew games that were on the card, without me changing them at all. Some of the games in specific are Super Collapse 3, MegaMan Powered Up, Every Extend Extra, Platypus, etc. Even worse, I recently picked up Hot Pixel, the actual retail UMD, and when I try to play that, it gives me the same "game could not be started," even when trying to play straight from the UMD. This part unnerves me a little more than just not being able to run a few games from a stick, when the damn thing won't even play my actual UMDs.

Is this a common thing that's been happening or does anyone have a solution? I also, afterwards upgraded to 3.90 m33 and then to 4.01 m33 to see if the upgrade would fix it, but it still does the exact same thing. I hope someone can help and much thanks in advance to whoever can.

First off welcome to the forums. Secondly, nice pic, love the smile. And lastly, all PSP games HAVE to be in CSO format. Although I have seen some people pull off playing ISO's directly. Anyway, what you might want to do is go into the recovery menu and change around some of the settings, as well as make sure that you are placing all your PSP games into the correct folder ms0:/ISO. Also you might want to double check under your settings that you have CFW installed. If neither of those are the problem and you already tried everything else just PM me and I'll gladly help out. Once again welcome to the forums.

Thanks for the welcome.

Yeah, its weird, cause ISOs used to work perfectly before, but I guess maybe its just a thing with the newer firmwares that they need to be CSO? In that case, is there a way to convert ISOs to CSO or would they have to be ripped again somehow? I see some programs out there that can do it, but are there any recommendations?

I definitely have CFW 4.01 M33-2 installed, just checked system info again.

I'll PM you the info.

I tried to convert 3 of the games that wouldn't work into CSO and they still didn't work, so maybe there's a better method or program than what I was using.

What OS are you running? Check your private messages. If you did sorry in advance.

The OS on my computer?

Mugen_NeS · 08-29-2008, 03:14 AM

Yep the OS on your PC. Is it XP/Vista, Mac, Linux?

Its Windows XP.

I just used the program you recommended, and the games still won't run. I also tried making them .dax and .jso as well, but neither would even show up on my list of games in the PSP. Is there something special you have to install to get those formats to run, or do they just not run at all?

No no no, ISO to CSO only. That is the best option.

Yeah, unfortunately those wouldn't work. I don't know what else to do

Mugen_NeS · 08-29-2008, 03:50 AM

Try impaler's or this one. I hope it works.

I converted all my other ISOs to CSOs last night and tested them all, and its so weird, because all the ones I wanted to put on my system to play this time were the ones that don't work. All the other ones I have (about 30 of them) all work just fine, but MegaMan, Platypus, Super Collapse, EEE, and Hot Pixel all don't even start. I guess I'll try some different rips of these games and see if I can figure anything out, but again, I don't mind so much on the ones that I ripped before, but even when it won't play the actual UMD in the system, it worries me.

I had that problem a few CFWs back. I went into the recovery menu (Holding R while booting up) [Don't know if you knew that, but seems like something to put out there, everyone here is so detail oriented] and fiddled with the UMD loading option. Some of those games need the option (Normal -UMD Required-). (M33 Driver -No UMD-) or (NP9660 -No UMD-). I just upgraded to the 4.01 m33-2 phat the other day too. The cool thing about toggling with those options is that it doesn't affect the psp much. At least not to my knowledge.... Hope this helps!

I fixed most of these problems by going into the advanced settings in the pre-boot and changing the options in there, but now when I try to play Xyanide, the game runs really choppy and won't play right. Has anyone had a similar issue with any games or know how to fix it?
