#Bad checksum error snes9x install
#Bad checksum error snes9x driver

Update: I got it working, but I ended up getting a HiFiBerry anyway for hopefully the best sound quality, and still had the issue. I am mounting the screen in my arcade cabinet above the main CRT screen and the pi mounts behind it so I don't want it to be too thick.

Hopefully the /etc/nf will work or HDMI will be listed next time since I didn't try to install the display driver. Edit: looking at the article, I saw the Mai item in Raspi-config thinking it was my Chinese made display, so that is what I selected. I appreciate all the tips, and I will give everything a shot until I figure it out, and it is no big deal to reload again if necessary.

#Bad checksum error snes9x driver

Thanks! I did try the Raspi-config utility actually and it ended up breaking the display output and I had to reload the OS from scratch - that or it was me trying to install the driver for the display that it did not need so maybe that broke it even though the script said it wasn't needed- not sure which caused the problem. For my USB Turtle Beach and HiFiBerry I remember having to manually edit a file (maybe /etc/nf) Its really been a while (and I was using RetroArch), but I thought that HDMI could be set it using the raspi-config utility. I'm the software from the Top 300 DOS games pack. I'm using the official Roland UM-ONE mk2 USB cable from my Mister to a first-gen MT-32. With just HIMEM, the MT32 checksum error occurs at startup of both SQ1 and SQ4 (regardless of whether DELAYSYSEX is set in SoftMPU or MidiLink.INI, unfortunately). So there’s no need to have MidiLink slow down the transmission, disabling L1 cache already seems to do that well enough.ĮMM386 MUST be enabled. If it’s TRUE then music starts playing late, after the Sierra logo has displayed for a while. Only the L2 cache can be enabled, otherwise the game runs too fast and generates buffer overflows and / or checksum errors on the MT32.ĭELAYSYSEX FALSE in MidiLink.ini. This balances game performance with perfect music performance, with no buffer errors or checksum errors:ĥ6 or 90mhz CPU (30mhz gets stuttering in game, 90mhz may make animations a bit faster than acceptable so 56mhz is probably a good middle ground) I'm using the official Roland USB cable and a first-gen MT32.Īfter many more hours of testing today, here’s what worked for me for perfect MT-32 playback on Space Quest 1 and 4 (and possibly other Sierra games of that generation). I do have 'DELAYSYSEX = TRUE' set in /media/fat/linux/MidiLink.INI which I thought was supposed to avoid these presumably speed related issues.
