Hello guys! I know this may sound like a pretty noob thing to ask and all, but I'm a noob lol I'm young and new to MSX overall, and I just installed and configured openMSX. I managed to apply the translation and the TurboFix made by sd_snatcher both in separate roms and they would be working on the emulator normally, but when I applied the other IPS on a ROM already applied with the other patch, the emulator just wouldn't read the ROM or something like that... I really don't know what to do right now, i'm not an expert in emulation or anything, I'm just doing a playthrough all Metal Gears, I would really be grateful if someone could help me out

Hi and welcome to MSX.org and MSX then. Does openMSX give a message when it doesn't read the file, this usually is an indication of why it doesn't read the file. To make life a little easier: openMSX can apply IPS files on the fly, so you won't have to touch your actual romfile. Then a word of warning. Applying a patch and another patch can break your file. Patches work on locations in the rom by replacing the code. If you mix patches that work on the same area or overlap, you might end up with very strange behaviour/hangs/resets etc.

To make life a little easier: file-hunter has the known working patched roms. OpenMSX recognises these rom's because openMSX has a database with the signatures of these rom's.

Nothing wrong with doing doing the hard work, but then: we also have sofa-run for the lazy penguins so enjoy MSX.

You have to be more specific: which patches exactly are you applying in which order and what exactly happens after doing that?
It sounds like the patches are conflicting.

It looks like that's what's happening, applying the two patches is breaking the rom :/ I tried looking for a rom with both patches in the file-hunter but couldn't manage to do it Sad

Hey Manuel! I Applying this translation here http://bifi.msxnet.org/mg2ss-eng/ and the TurboFix made by sd_snatcher, I tried in different roms and applied them in both orders possible, first the translation and then the fix and the reverse order... But the result was the same, the openMSX asked of which mapper I would like to use but doesn't matter which one I choose, it will always say that the file couldn't be read. Oh, and I used LunarIPS for this!

What error are you getting exactly?

Those 2 patches do not conflict. When you have to select the mapper type, you must select Konami with SCC (maybe Auto-detect will also work, not tested).

@Kemornian

What's the SHA1SUM of the ROM you're trying to apply the patch?
