"Error While Loading Rom" and IPS Patches Issue

[clydesdale]

Greetings,

First off, let me say thank you very much for all your hard work on this fantastic emulator! The progress on each build is amazing!

Currently, Im using s9xTYL 0.4 ME on a 1.5 PsP and experiencing this oddity:

Quite a few IPS patched roms (Translated and Hacked) that used to load up fine in s9xTYL 0.3 ME, are no longer loading in the current build (0.4 ME). I have been using these these Roms with the IPS patch already applied. When I try to load them in 0.4 ME, I get a "Error While Loading Rom" message, then usually the "blue screen of death" resulting in a crash. Here is a list of the Roms showing the issue, perhaps you could narrow it down to figure out why they dont load anymore =).

Do-Re-Mi Fantasy - Milon no Dokidoki Daibouken (J) [T+Eng.99_Gaijin]

I should also note that quite a few other IPS patched Roms are working fine, so its not happening with all patched Roms, just the few listed above. Thanks so much for looking into it. For now I'll just keep 0.3ME and 0.4ME installed on my MemStick so I can still play all the great translations the community has provided.

try manually patching the rom with an ips patcher so u don't have a separate .ips and a separate rom file. worked for me for a few

[clydesdale]

Thanks for the reply Manias, these are manually patched here. I tried having separate files with them as well, but usually ended up with graphical errors <shrug>. Appreciate the response though bud =)

Edit:
After testing a few more things, I found something else wierd. While the above listed IPS Patched roms do work in 0.3 ME, they only work after loading any commercial rom first, then returning to the browser and loading the patched rom. If I try to load the IPS patched rom first, the emulator crashes. Strange stuff!

[manias]

why, you're welcome
do they also crash without ips's?

[clydesdale]

Nope, thier japanese counterparts load fine

-Also I should note that the trick of loading a commercial rom first does not work with 0.4 ME.

If you use the T-Eng translation for Do-Re-Mi Fantasy (instead of T+Eng.99_Gaijin) than the game boots fine, but after I loaded my save state it crashed when I tried to enter a level. But if I start a new game I can enter the first level without it crashing.

thanks clydesdal for the clear report
I'll have a look as soon as I can.

it's weird, I just tried super demo world : tlc (1.1) and it works well.
as asked in the ips patch file, I have extended to 48Mb ExHIROM my smw US rom and then patched it on pc using a standard ips patcher (lunar ips).
after that the patched game is working well in s9xTYL.

you should try to go back to the original, good dump of the games and apply the ips patch by yourself.
sometimes prepatched game are "not clean" and s9xTYL does not like them much... :-(

Maybe it has something to do with interleaved and Non-Interleaved ROMS?

What is the difference between Interleaved and Non-Interleaved?

Interleaved means that data was scrambled from how it should be. Imagine a ROM was broken into 10 parts.


Non-Interleaved Interleaved
0 1
1 3
2 5
3 7
4 9
5 0
6 2
7 4
8 6
9 8



Where does interleaving come from?

Interleaving comes from one of two places. Either the person who copied the contents of the ROM to his computer was using a copier which interleaves the ROMs, or someone made a mistake when changing the ROM.


Is it good to have interleaved ROM dumps?

If you want to play your ROM dumps in an emulator, it is better to have them in non-interleaved. Some emulators can detect an interleaved ROM, some can not. If your ROM is interleaved, and the emulator was not able to put the pieces back in the right order, the game will not play correctly.

Some translation patches are made with an interleaved ROM, thus requires them to be patched an played.

Figured it out! I feel stupid too, it was right there beneath my nose

In my effort to include the Japanese/Translated/Version Number/Author all in the Rom name I guess I made em too long! **This crash bug shows its ugly head when a rom's name is to lengthy!**

Not sure if this would be considered a bug YoYo, but there ya' go. Narrowed down to my verbosity <snicker>.

Thanks for all the help folks extended, and sorry to waste anyones time.

I confirm this problem. When the name of the rom is too long it gives ERROR! ;D
