rmilyard Posted June 7, 2016 Author Share Posted June 7, 2016 So today I have been adding systems to LB. I haven't really messed with configs/setups right now just getting the added and all media downloaded. My question is almost all my ROMs are either 7z or .rar so if this going to cause issues? In most of the tutorial videos the ROMs are not compressed. Quote Link to comment Share on other sites More sharing options...
SentaiBrad Posted June 7, 2016 Share Posted June 7, 2016 Because compression takes a lot of time for decompression, so it is suggested to not do this for Disc based systems, and on the earlier cart based systems you don't save that much space in the grand scheme of things. That said, we do know people like to use it regardless, and as long as you check the Box when you edit an emulator to use Archive Compression (to decompress it), then it will work just fine. Just make sure to disable that check box for games that can't be decompressed, like Arcade systems. Some emulators also natively support archives as well, in which case that is prefered. The alternative I prefer and suggest the most is to not use archive compression, but alternate compression. PS2 and PSP games can be CSO compressed, Gamecube games GCM compressed, Wii games can be WBFS compressed and PS1 games can be PBP compressed and it will eliminate the multi-disc issue as it should automatically switch discs. Some games don't like being put in to CSO, PBP or GCM containers though, and there are compatability charts for those systems on the internet. Search the forums for those compression methods if you're curious, we've talked about them a lot on here. Quote Link to comment Share on other sites More sharing options...

SentaiBrad Posted June 7, 2016 Share Posted June 7, 2016 Yes, it's per emulator. Quote Link to comment Share on other sites More sharing options...
rmilyard Posted June 7, 2016 Author Share Posted June 7, 2016 SentaiBrad said Yes, it's per emulator. Hmmm. Maybe future should have per platform? Just thinking out load but since RetroArch does so many systems might be handy. Quote Link to comment Share on other sites More sharing options...
DOS76 Posted June 7, 2016 Share Posted June 7, 2016 With RetroArch you can actually end up needing to use compression for some systems but not other and you may need to keep two instances of the same emulator in LB to accommodate for both of the settings.
