DOSBox AGA/RTG

Strange, i remember doing it thanks to a piece of advice given here on the forum, but perhaps because of old age
Meanwhile I did a test of the game Electro Man on WinUAE with AFA-OS, here is the video:

Thanks for the video, how many cycles did you use?

Try switching to the 'normal' core for emulated platforms as it's more stable than the 'simple' core and supports more CPU's.

I'm sorry, I don't understand. Do I need to change something about WinUAE? what particular options?

No, it's in the DOSBox configuration file.

For a real Amiga or FPGA it should be something like:

PHP Code:

[cpu]
#      core: CPU Core used in emulation.
#            Possible values: auto, normal, simple.
#   cputype: CPU Type used in emulation. auto is the fastest choice.
#            Possible values: auto, 386, 386_slow, 486_slow, pentium_slow, 386_prefetch.
#    cycles: Amount of instructions DOSBox tries to emulate each millisecond.
#            Setting this value too high results in sound dropouts and lags.
#            'fixed #number' will set a fixed amount of cycles.
#   cycleup: Amount of cycles to decrease/increase with keycombo.(CTRL-F11/CTRL-F12)
# cycledown: Setting it lower than 100 will be a percentage.

core=simple
cputype=386
cycles=fixed 1000
cycleup=10
cycledown=20 


And for WinUAE/Amithlon/AROS it should be:

PHP Code:

[cpu]
#      core: CPU Core used in emulation.
#            Possible values: auto, normal, simple.
#   cputype: CPU Type used in emulation. auto is the fastest choice.
#            Possible values: auto, 386, 386_slow, 486_slow, pentium_slow, 386_prefetch.
#    cycles: Amount of instructions DOSBox tries to emulate each millisecond.
#            Setting this value too high results in sound dropouts and lags.
#            'fixed #number' will set a fixed amount of cycles.
#   cycleup: Amount of cycles to decrease/increase with keycombo.(CTRL-F11/CTRL-F12)
# cycledown: Setting it lower than 100 will be a percentage.

core=normal
cputype=386
cycles=fixed 8000
cycleup=10
cycledown=20 


I've attached the latest version to this post, not much has changed...just fixes to the mouse.

i set in emulation auto for "core", "cputype" and "cycles". Games run very smooth.
i try to rename default ".conf" in DOSBox.conf, but then DOSBox don't run.
i try also to set the mount in root like PC version, but don't work. Normally i set: Mount C . to have C: in the root of directory where is dosbox.exe

Not sure why you'd want to rename the config file?

For mounting I use 'MOUNT C Work:' which mounts my Work: partition DH2: to PC DOS C drive

[Seiya]

rename because used to use dosbox.conf, but not problem to leave it with it's predefined name.

No, ElectroMan with these parameters on WinUAE everything is slower !

core=normal -> Slows down "a lot" the game

cycles=fixed 8000 -> slows down the game

Tested Tomb Raider and after the logo I have the error that you see in the screenshot, on DOSBox PC works well.

and what parameter do you use?

With these parameters (the default ones) ElectroMan is very fast (see attached video)

I will test it thanx

BTW I just tested DosBox on Aros Vision and it works excellent

Thanx for the new version

Yes also on AROS 68k (Nightly Builds) works well DOSBox RTG, only problem is that the audio does not work

the default parameters did not work at me (slow) but with parameters of Novacoder it is fast (f.e. Doom)

On Aros Vision I have Sound (just tested with Doom)

@NovaCoder
but Amiga DOSBox not support the command "imgmount" to mount cd-rom iso or at least when i try that command it seems it works, but really it works?

you have to set graphic card (from dosbox-0.74.conf) to SVGA_Paradise or SVGA_ET4000.
The problem is that Tomb Raider change automatically screensize and Amiga DOSBox seems not suppor this feature

Nope, my 68k ports do not support CD-ROM drives or iso's unfortunately.

Don't use the simple core with tomb raider, try the normal core.

Ok the audio works well on AROS 68k, in the last release of NovaCoder, the audio was disabled in the configuration file (dosbox-0.74.conf).

Changing Graphics Card there are no more errors, but in addition to the slowness the game is not loaded, Tomb Raider also used the 3DFX. Tested also DOOM2 that starts but is too slow.

Test AROS 68k (Games ElectroMan):

Looks good

You should try running ElectoMan in window mode and then press CTRL+F6 to increase the cycles and CTRL+F5 to decrease the cycles until you find the best balance (speed).

DOOM 2 needs at least 8000 cycles with the simple core, it will be useless at 1000 cycles.
