mame confusion with "missing files" error and bio location

[REPGAM]

ok ill try and make this short. i have the latest version of mame but want to play marvel vs capcom 2.
but when ever i start it i get the "missing files" error.
after some research i found a zip with bios in it ( [bios pack] --inside--> [lost of zip bios])
i tried putting the whole pack into the rom folder with no success and tried putting all of the zips in to the rom folder but still nothing.
please help.

MAME is a little weird compared to most emulators. When arcade games started getting ripped and uploaded online, a lot of the time they were imperfect rips, and versions of MAME were written to work with those imperfect copies. As newer, more complete copies of the games are released, MAME is updated to work only with the newest game rips out at the time of release. What this means is that some arcade roms will only work with very specific versions of MAME.

I've always had issues figuring out which version of MAME I need for any particular rom, especially when downloading just the single rom, i.e., not as part of a set. That said I would recommend looking for a download for the game that includes the proper version of MAME; torrents will probably be your best bet if you know how to use those.

Also if your computer can handle it, there's also both a Dreamcast and PS2 version of Marvel vs Capcom 2, so you could try emulating those instead. With PS2 games sometimes certain versions of the emulator (PCSX2) work better with certain games, but there's an entire wiki dedicated to the emulator showing what version works best with each game. You can find their page for MVC2 here; http://wiki.pcsx2.net/index.php/Marvel_vs._Capcom_2

You can either go for an easier arcade option and grab FBA (Final Burn Alpha) and the rom that goes with it from http://www.emuparadise.me/Capcom_Play_System_2_ROMs/55

Or you can use MAMEUI and audit the game that will give you a report on what exactly is missing and from what folder (the folder reported = the zip file the files are looked for in)

MAME is easy enough to use but lots find it difficult mostly for this exact reason

At a guess you are missing the Q-Sounds rom used by CPS2 (Capcom System 2) games, like Marvel vs Capcom 2 you can get that at http://www.emuparadise.me/M.A.M.E._-...Q-Sound/164687

The bios pack does not include anything for CPS2 roms but yes the zips should go in the roms folder, but not the main bios pack file, to be honest that pack is out of date and you are best getting each bios image seperate

i found the files, put them in the mvsc2 zip and ran it in an earlier version of mame. it loads but i just get a sceran saying thats its not working and i should wait for a dev to make a emulator for it.

what I linked should of been kept as is and stored in the roms folder and a newer version of MAME used

as far as that message you can ignore it chances are unless you are using a very very very old version of MAME the game works fine

i fond the files that where missing and placed them in the game folder. so now it works....only super slow lol if its not one thing its another

The best you are going to get on a low end machine is via FBA or another alt arcade emulator, MAME emulates for accuracy but that is at the cost of speed especially for lower end computers
