Apparently some of the printing breaks in recent gccs (maybe gcc 11) with -Werror=format-security This breaks, for example, the ubuntu jammy builds: https://launchpadlibrarian.net/610693096/buildlog_ubuntu-jammy-amd64.dosbox_0.74-5-3+lp20220701~ubuntu22.04.1_BUILDING.txt.gz Just letting you know you …

You can't script as soon as you require user input. In this case, that 'press f5'. And i'm not going to require something like autokey (not that it would work in wayland, which is my desktop, since its security doesn't allow control of user input iirc). Besides, i tried the manual step as i said and …

I tried that approach with the images produced by parted/mformat above. It didn't work. Also to be clear i want a approach that works completely outside dosbox/DOS/Windows and user interaction. Fire and forget and never do that stuff again, preferably without touching sudo. I've 'done it' (the …

Speaking of this i've tried to make a way to transfer windows 95 and 98 to a bigger or smaller disk (like certain universities are able to image a OS into a networked machine), but i've failed. https://gist.github.com/99215a27097594d4e3f50bdc8f8fe8ad I tried this, using the mtools package and parted …

He probably meant fat32 'transparency' usually wanted for windows 95 booting. And the answer is 'functionally impossible without replacing windows 95/98/whatever, because dosbox doesn't emulate windows and thus the windows drivers take precedence and passthrough is impossible'. The reason wine is …

I don't have a pi but i definitely built libmt32emu before for ARM64 for dosbox in my ppa; though i suppose this topic is more of a hardware addon module.

@kekko, i just updated the patch to the latest version on the ppa, and it failed building. I think it's because of a path separator thing in a header include, and i'm going to edit the patch to see if it is, but i thought you should know: https://launchpadlibrarian.net/486219180/buildlog_ubuntu-eoan …

Ok, time to update the build anyway, since the other part of this patch is broken since r4343 I'll probably wait until the github mirror i'm using updates and that breakage becomes 'official' if it ever does. Why can't sourceforge have github mirrors for the svn repositories it has automatically …

There is a mistake found by the dosbox-core fork for retroarch on this patch : https://github.com/realnc/dosbox-core/commit/3ff648cf3bcd3a131d6eebb4249b3d646d031541 There is also this but i suspect it's irrelevant for non libretro environments: https://github.com/realnc/dosbox-core/commit/ …

I added the shaders to the ppa. I renamed them slightly to clarify some names and always follow the convention crt_NAME for the user to easily know what's for a CRT shape or not. At least, i hope that's what being placed on those dirs means. Underscores is just because it's a informal convention in …

I've got something almost working. I' saying 'almost' because i'd like to install (or rather to copy over) the OS into another bootable drive from linux and start it up. I tried ms-sys but it didn't really help, and i tried the native tools (without formatting) with a bootdisk and a fdisk /mbr and a …

Ugh. The only easy non-root way to make a dos filesystem in linux appears to be mkdosfs, and it uses the C/255/63 addressing scheme (well, it uses blocks, but i can do the calculation easily by dividing and fdisk -lu=cylinders gives those values). I'm going to give up on C/240/63 and test things out …

Still trying to figure out what your end goal is to do all this. Are you looking for dynamically creating Win95 bootable image at variable sizes or simply documenting the procedures in readme or writing up a scripts? Frankly, DOSBox disk image support has been leaving something to desire. QEMU …

I'm very suspicious of the autodetection these days. Why couldn't dosbox support one of the formats where autodetection is not needed anyway? Do these problems exist with qcow2?

I'm willing to waste a bit to only vary cylinders and have less size available to have compatibility with other 'low level emulators' for the images that use real bios. For input in human readable form i'm using the gnu numfmt. Since this is for a package and not a 'portable' utility i decided to …

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 …
