Interesting! I'll have to give this a go.

Although the prospect of MSDOS gives me the shudders as I recall my job in the 90's which for the most part was spent resolving crashes in software due to lack of memory while sorting huge amounts of data and having to squeeze every last possible ounce of memory out of the machine to get time critical jobs out of the door

DOSBox 68K RTG also works perfectly on AROS 68k, fast, good graphics and good audio, see test video on AROS 68k.

Thanks for the video, nice to see my hard work being put to some use

RTG version crash the gui when i want to close dosbox. i tried with Amikit and WinUAE with AmigaSYS.
gui freeze and i forced to reboot.

Strange, works okay for me?

Did you type exit or just close the window?

[UberFreak]

Performance on WinUAE is pointless, how does it perform on an 060 Amiga?

Thanks for working on this, NovaCoder!

[MartinW]

I can probably give it a try this evening if I remember. I have an 060 @ 100mhz with RTG

I’m interested in taking it for a spin anyway

[nobody]

Why would anyone run this on WinUAE and not just run dosbox on PC? I assume performance on real (fast) 060 would be 286 level at best. There are some good games that run on XT too but usually the Amiga had the better version.

Seiya, i did a test and I had no problem with Amikit, the window can be closed with mouse or with exit command, see attached video, which graphics card are you using?

i try just close the window

Tested Amikit with Zorro 32 MB and it does not work well, DOSBox closes on its own, try with 128 MB, , with Zorro 32 MB no problem on my AfA-OS systems

I was not able to test - just get "Unable to connect to database" from Aminet.

Will give another try when it's back up

Well I did give this a go because I'm interested in anything that might run on my graphics card but sadly, I don't have anything old enough to be a reasonable task for it.

Quite an achievement though!

There was one quirk - if I mounted the root of any of my drives, so let's say "mount C DATA:" then while it mounted and I could go to drive C no files or directories were found. If I mounted

DATA:DOSGame

instead (for example) then it worked as expected.

Yep I always mount it to something like Work:Games, never to the root.

I'll attach something nice and old for you to test!

If you do try it on real hardware or FPGA/WinUAE/Amithlon then make sure you set the correct core and cycles in the config file.

For real hardware you should use the 'simple' core and cycles set to say 700 (fast 060, don't even bother with an 040). If you have a fast FPGA then you could try the 'simple' core with say 1,000-3,000 cycles and on WinUAE/AROS/Amithlon then it's better to use the more stable 'normal' core and a setting for say 10,000 cycle (depending on how old the game is).

[MartinW]

Cool. I’ll give that a go tomorrow hopefully. I was never big on dos games for some reason although there was an RPG series I liked. I don’t think I could afford a PC of my own until around 2000 and I didn’t really need one as I always had a company machine at home that was refreshed very often because of the work I did but I couldn’t put games anywhere near it.

I have Heretic and Hexen and it’s cool to see them running in DOSBox but I already know from the main thread that it’s not reasonable to expect either of them to run well. And there’s little point anyway when they both have native Amiga exe’s

There’s probably a whole bunch of dos titles I barely even know about!

[NovaCoder]

No idea how many cycles this was using but DOSBox RTG is working pretty well on Vampire. An old VGA adventure game or dungeon crawler would probably be playable.

I'd call that a success considering how friggin demanding DOSBox is to run (runs slowly on a Pentium 166 apparently).

Excuse me NovaCoder i forgot, could you tell me the parameter to enlarge the window ? i would like to test Electro Man on AfA-OS.

Sorry but my port doesn't support scalers so it just uses the game's native resolution in both full screen and window modes.

I'm going to upload a new version soon with updated mouse handling soon
