Hi all, I just built an arcade cabinet out of a dell Inspiron 630m and am having a bit of difficulty. Every time I run a psx game the screen goes black and I see the logo and back to the xmb.
Snes, Genesis and my other roms work. The way I’ve been transferring files is by booting a live Ubuntu and dragging roms over to the storage folder.
I have already tried placing the bios files in the system folder and using a nightly build and have no idea why this is still happening…
Thank you, Ramin
Hello, sounds like a missing BIOS issue. Check our documentation about BIOSes 
Thanks for the reply.
I did put the bios’s in the system folder and also renamed the scph1001 to 5501. Is it as simple as drag and dropping to the system folder or am I missing something?
I don’t think renaming works anymore. Find one that matches the checksum.
SCPH5000 is the only one of the required ones that seems to work outright.
SCPH5001 doesn’t seem to exist anywhere; but 7501 (or was it 7001?) works if you rename it to 5001.
SCPH5002 does exist, but based on the CRC32, it’s not actually the one Lakka is looking for, and thus it will not work. The one you want to get is 5502, and rename it to 5002.
Ok so I got the emulation working by doing a md5 hash check and making sure the right files were there.
My next question is how can I improve the emulation, it’s extremely slow and choppy for all games. Are there any settings I can change so the games become playable?
My system specs are pentium m single core 1.73 ghz with 2gb of ram and Intel 915 built in graphics.
Thanks!
Turning off shaders (under the core’s settings), and maybe turning down the window size (under the general video settings), might help? I tried it on a slightly more powerful system than that (Pentium D - not sure of the speed - with a dedicated 256MB ATI card of some kind; I don’t have the PC with me at the moment so can’t check) and it mostly plays at full speed but still has some nasty graphical glitches on most games; only ones that seem to be relatively free of them (at least out of what I’ve tried so far) are Bust-a-Move 4 (no glitching at all) and Spyro the Dragon (glitching is present but almost unnoticable).
Mednafen-psx doesn’t use a dynarec or hardware-accelerated rendering, so it is very demanding as compared with ePSXe, for example. Typically, a core2duo or higher is recommended for hitting full speed reliably.
What about pcsx_rearmed? Is it less demanding?
I’ve been interested in pcsx-rearmed but can’t find a build with it already in there. Is there a way to add cores using ssh?
pcsx-rearmed is less demanding on ARM hardware but not any better on x86/64. In fact, it shouldn’t be used on x86/64 at all, as it’s very buggy.
Cores are just SO files, so I’m pretty sure if you got a copy of it (in that format) from somewhere it should work? However - I believe PCSX_Rearmed isn’t very good for use on PC hardware?
As it’s name states, it is optimized for ARM. I was able to run it on PC and it was pretty slow too.
