whazzzzzup17 Posted February 9, 2020 Share Posted February 9, 2020 As the title says, on other platforms, I don't need to extract my ROM's and can leave them in their zip containers. I currenlty have two folders MAME/ROM's/GAME.zip <---ROM's MAME/CHD/GAME/GAME.zip < --- CHD Both have the zip files, however, I can only get MAME to work if I extract the CHD zip files. Is there anyway to allow Launchbox to extract the CHD when I play the game, so I can leave all my CHD zipped? Quote Link to comment Share on other sites More sharing options...
Retro808 Posted February 9, 2020 Share Posted February 9, 2020 Mame chd files need to be extracted and in a folder named after the rom. That folder then needs to be located in the folder where the mame zipped roms are. That is where it will look by default. Unless you tell mame where to look directly by changing the file mapping.

whazzzzzup17 Posted February 9, 2020 Author Share Posted February 9, 2020 Understand that, but is there anyway to not extract the chd and keep the folder structure you mentioned. Then have launchbox extract the chd when you play the game. On Launchbox, within Emulator settings, it gives you the option of extracting the ROM zip file when you play the game.

You could modify the MAME.ini to keep them separate. # CORE SEARCH PATH OPTIONS # homepath . rompath roms;e:\mame\roms;E:\mame\chd hashpath hash samplepath samples artpath artwork ctrlrpath ctrlr inipath .;ini;ini/presets fontpath . cheatpath cheat crosshairpath crosshair pluginspath plugins languagepath language swpath software Quote Link to comment Share on other sites More sharing options...
Retro808 Posted February 9, 2020 Share Posted February 9, 2020 Ahh. I missed that part. You could probably make a second Mame emulator that is used to launch only chd games. Then check the unzip option in it. And my post did directly say you could change where Mane looks for the chd. Quote Link to comment Share on other sites More sharing options...

I don't think it can reference both at the same time. It extracts the CHD but then can't find run the ROM. I'm trying to do it with CarnEvil and it fails, unless I extrat all the CHD's prior.

Yeah this may only work with the few chd only games. So you may be out of luck. Quote Link to comment Share on other sites More sharing options...

Just curious. It would be easy to update future MAME sets, instead of waiting for the 500gb+ CHD's to extract. Quote Link to comment Share on other sites More sharing options...

But considering how few working chd games there are I rarely update them unless the change log shows those games got updated. I havent downloaded a new chd in quite a long while.

Just getting into MAME and didn't realize that so that's good to hear! Thanks for the help. Quote Link to comment Share on other sites More sharing options...
DOS76 Posted February 9, 2020 Share Posted February 9, 2020 Having a CHD game zipped is redundant as its already in a compressed format. Quote Link to comment Share on other sites More sharing options...
