And, fdisk gives you precisely the partition type to set. If toggling LBA flag in parted did not work, then you just use fdisk to create the MBR partition and set type. man sfdisk gives the impression that it was completely removed with: Since version 2.26 sfdisk supports MBR (DOS), GPT, SUN and …

Ah, another question. Wouldn't it be better for compatibility of the bigdiskCHS_8G patch to use the limit of the later ECHS of 240 heads (leading to 1024/240/63 - 7560 MB)? That would make images compatible with other emulators and bios that 'care' about being hardware accurate no? Also why limit …

This is basically for simplifying the horrible 'readme' that appears when you install the ppa and for making the workflow easier.

Right. I was hoping there could be some safe autodetection for this so that when running dosbox in Retroarch the user can just select an image to mount in the GUI. It's not possible to specify a geometry by hand there, you just select the image file. I guess I could kludge this by having the user …

So, i'm trying to make instructions to make it easier for 'normal users' to use dosbox to run windows 95 games in linux (yes yes heretical i know).

The main problem with running win95 games in dosbox is that the process is highly technical and dosbox doesn't emulate the cd hardware, so win95 drivers can't 'see' mounted isos. It *is* possible, if you 1) can be assured to have a 'clean' win95 hdd image (i use a ramdisk copy in linux for this, so …

BTW this really should be something upstream does, when a glshader is turned on, turn off the normal scaler. Combining a software scaler and a glshader seems like a recipe for unnecessary pain. In fact maybe it would be better to 'pretend' both use the same mechanism in the conf file just to …

To people trying the above glshader, you'll get better results if you turn off the scaler (with 'none') before using a glscaler (not only this one).

Another world intro and crt-geom and normal2x has a funny wobbling effect that's maybe a bad interaction between the shader and scaler. You can avoid it by setting none scaler when using a glshader.

If it's in the right folder you can already use them by name only. You're missing the point maybe, i can't place glsl files on a user dir during a package install because it's not allowed, and if it was it would be broken as soon as the user deleted the dosbox conf home. Package files need to go …
