Hi guys

I recently acquired a Pistorm-equipped A500 Plus and I am amazed and totally love it, with the speed, the extra memory and better screenmodes.
However it appears I was wrongly under the assumption that it would run AGA games (I may have got mixed up with the Vampire?) from iGame.
So I guess the question is, there a way to get AGA games to run - on what is, essentially, a much more powerful machine than the stock A1200/4000 they are written for.


I do have an A1200, but this I was hoping this would be placed into hard-earned retirement with this beautiful more powerful setup I have.

I wonder if there are any efforts underway to make updated RTG versions of AGA games as we exit the AGA era and into the RTG era with our classic machines.
Or if there is a hack that can make the RTG on our Amigas "mimick" AGA for legacy compatibility?

It would be a shame if I could no longer play delights such as Gloom, Banshee, AB3D2 on my Amiga.

Oh and happy halloween everyone :)

@plechaim

I do not think so. PiStorm uses the original chipset. WHDLoad also when started takes over the system but needs chipset from hardware

from a website:
My recommendation is the A1200 for AGA. it has the good compatibility with older games (when using WHDLoad), its cheaper that the Amiga 4000 and much easier to find.I could also recommend the A600 if you don’t want/need to play the AGA games Its smaller than the Amiga 500+ and slightly easier to add a HDD.

so it seems not

on apollo V4 cards it is different, those include SAGA, that is compatible to AGA

RTG versions of AGA games? Certainly not. The concepts are very different, RTG based on API calls of the OS, AGA games taking over system and directly hitting hardware using chipset. Different worlds.

The latest version of AB3D2 on aminet should run on your machine as long as you have a 320*240 (or better 320*256) 8 bit screen mode available. It only requires AGA if you don't have RTG available.

Pistorm / Emu68 is an accelerator card for your Amiga, not a "chipset enhancer".

You can play AGA games if they support RTG as well or if the AGA support is limited to the requirement of 2 MB ChipRAM and/or 68020.

UAE 68k is too slow on Pistorm if you enable everything, even with Pi4. It might be usable without sound and with frameskips. But it doesn't make any sense anyway. Why emulate a full Amiga on 95% the same hardware?

@Karlos

why do you mention AB3D2 here? He asks about AGA games in general

@_analogkid_

normally AGA and RTG are different versions. And that certainly are rare cases where both is available

You don't need AGA for AB3D2. It works fine on ECS systems that have RTG.

Oooh :)
Thank you, I will check it out.

@plechaim

Make sure you add the AB3: assign pointing at the game directory to the startup script. I forgot to include that fact in the readme. Other than that, just replace the tkg binary with the 040 version id toure on Emu68/Pistorm

cause you can? I just saw it seeing done in ham, thought it to be cool... now with the ppc being on the cards, it might bring it the necessary speed, just more possibilities one can try

Gloom Deluxe also supports RTG, simply select the right screenmode in the config application (called "Gloom config", I think).

Sadly only few AGA games have RTG versions.
You may also try Mac emulator (eg. Shapeshifter), some "AGA" games even work better there than native (Sim City 2000). Back on my A1200 (50 MHz 68030 and plain AGA) I also played demo of Warcraft I, it should work really well on your setup.
Speaking about emulators... why not try DosBox? Could be fast enough for not that much demanding games (eg. Civilization I - sure there is a Mac version, but I prefer the DOS one ).

Edit: If you go the DosBox route, I also recommend the DOS version of Populous II, but it requires at least 3000 CPU cycles for low resolution.

@plechaim

Many monitors have more then one video input, so you select video input on the monitor,
you can also get keyboard, video, monitor switch (KVM)…

AGA games that was ported to RTG games, a lot of this Amiga games have been recreated for Linux/Window on SDL, and back ported to Amiga, not accrual original game. It happens but its not that common. Unless it was high quality game.

AGA emulation needs a lot of CPU power, the advantages of having real hardware will be gone, you might as well run WinUAE or something.. there is a version of EAUE for AmigaOS 680x0, I think its really old. have a look on Aminet

Amiga's E-UAE 2025.6 running AGA game on the Amiga 500 with PiStorm-Emu68 with RPi CM4

Amiga's E-UAE is being updated.

The proof, as always, is in the puddin

@pixie

i think this one is more realistic...

https://www.youtube.com/watch?v=MbgdGtCzr6M

some stuff will run under EUAE, and might be fin, other things perhaps not.

the only advantage as see it, EUAE does not block downloads, or music playback in the backgrounds.
sense many old games are not system friendly, sadly. and you don't need to switch video output, or need a scan doubler (sense many monitors do not support 33Mhz).

Most of the late period Amiga 3D games do support GFX cards with higher resolutions and speed than you could get from AGA version.

But you must have a working CGX / P96 installation.

Here it is on running on a CCTV with Indivision ECS and a 68030. Your pistorm will utterly crush it.

Indivision ECS v4 has P96 RTG via Denise socket I/O.

From https://forum.icomp.de/index.php?thread/3629-indivision-ecs-v4-new-features-development-progress/

- Framebuffer mode with 256 colours out of 21-bit colour, 1024x768 and 1280x1024 pixels
- 2D acceleration to framebuffer mode.

It's an interesting "What If" upgrade path for a drop-in upgrade on the Denise socket.

Baseline Amiga wasn't designed with PC's partitioned graphics architecture.

------------------------------

The Amiga had an early 1980s unified game console-style graphics/audio architecture that evolved into the 16-bit generation since it was spec'ed from 1983. Other later mainstream 16-bit game consoles have discrete graphics with very high bandwidth 64KB VRAM.

In the recent era, UMA makes its return with LLM since large capacity GDDR6-20000 is not cheap enough when compared to a 256-bit bus with common LPDDR5X-8000+ chips.
