Blitter Emulator

In the AW.net thread about OS4's new planar emulation, it was mentioned that a blitter emulator might make a few more old apps work (such as DPaint3 or Brilliance).

Edit: With 0.3, it seems to work quite well.

Anyway, click the link below to download and try it. I take no responsibility for anything bad that happens as a consequence of people trying this out.

Info and download page

@xeron

Can't help you with information, I've forgotten most about programming the chipsets. Just wanted to say that it would be a very cool thing if you got this going, and I hope you will :)

@orgin
Well, I hope so to. Whats done so far at least proves that the concept works; DPaint 3 is closer to working with blitzen than without it.

Who knows, maybe it already helps other apps work, but I didn't want to get anyones hopes up, since its far from complete.

@xeron

and btw.. ask kalms or booger.

@spotUP

huh.. where did my first post go.
a short one again then, thumbs up xeron! nice one!

@spotUP

on AW.net, perhaps? :)

OK, 0.2 is up already :)

Changes:

? Fixed small problem in copy/fill mode. DPaint 3 works a lot better. Its round brushes look correct as long as they're not wider than one word (for some reason, when the circles get wider than 16 pixels, the leftmost word of each line is repeated as if the source pointers aren't updated. Don't know why yet). And its smooth-freehand mode looks a lot better (although not perfect because of the same bug).

? Line mode is implimented using the same algorythm as MESS, but i've not tested it yet (if someone wants to make a program to specifically test it, please do. Just remember to make it a 68k exe otherwise WaitBlit() won't wait for your blits :)

I don't think Brilliance will ever work, though, because it uses full on copper magic.

Hi,

very NICE idea

And .. if run your BlitterEMU good ...
The next step is the Amazing ChopperEMU

So .. at the end .. only for very hardcore HW banging
Games eUAE is needed ...

This would be a good reason for all the hardcore classic
user "i buy not an -Amiga- to run en Emu to run old Amiga
soft" come to OS4 ...

Copper emulation is not really feasible.

Blitzen 0.3 is ready!

It now makes all the drawing tools in DPaint 3 work correctly. DPaint 3 isn't exactly completely usable, though; tools which draw crosshairs or zoomboxes leave trails all over your picture. I don't think they're drawn with the blitter, so that is outside of the scope of blitzen. It also freezes up sometimes, which is annoying.

I now consider Blitzen good enough to be useful, though. Other apps that use the blitter directly on intuition screens should work with it.

So, everyone, download 0.3 and try some old apps and see if it makes them work better. Report here if anything does. Remember to turn on "Planar screens on RTG" in GUI prefs, and make sure that fake native modes are enabled.

@xeron

Great Work! :) I'll try it out.

Cheers,
Bean.

@xeron

Well, I'd say a basic Copper emu would help on old demo/intro programs to work. Under basic I mean, screen opening/closing + palette setup.

Oh, and BTW: Nice work!

@Chip

Well, I'd say a full-featured AGA emulator would help with running some old apps and games...

@All

Has anyone give a tought about classic sound emu?

Hi,

Why not create a seperate Forum ...?
Like "ClassicEmu Forum" ?

To bring all OS4 classicEmu soft under one Point,and his
development.

Petunia [68k EMU]
Blitzen [AGABlitter EMU]
....... [AGAChopper EMU]
....... [Paula EMU]

This is easyer to follow .. and the OS4 user that dont
need classic soft and this Emus [or dont care] can concentrate
on OS4 native problems.

Just out of curiosity. Why do you call it Chopper?

HI,

@fjudde

i look to much Anime [in this case -> OnePiece ]

@jape

NallePUH for OS4 is available since ages

@srupprecht

IIRC that came unusable after UPD 3
