Trying to build the ultimate Commodore/Amiga machine

jamrom2

@George-Spiggott using the lr- versions you can dumb down the system core a little, sometimes that helps with games that seem like they're slow, but actually the core is running too fast. I think Amiberry had that as well. It's not a cut and dry emulator on either side. Because it's emulating many versions of 1 name brand, and ever expanding versions of that product, you have to tweak it for different games. I had an A500 back in the day and I remember there were games I couldn't play because I didn't have the memory spex. The first time I ever came across that on a computer coming from using a C64. Then of course with PCs it was status quo.

@George-Spiggott I have the images, which is why I was curious and where do I put them.

@Jiryn

all properly named kickstart roms go in /home/BIOS

The game roms go in either /home/roms/Amiga or .../CD32

@sirhenrythe5th @jamrom2
Mine is named
"[BIOS] Kickstart (USA, Europe) (v1.3 Rev 34.005) (A500, A2000).rom"

So will I need to rename them?
I have 33 different KickStarts, do I drop them all in?

@Jiryn I can only speak for Amiberry. Since version 5.x the KickStart roms must be stored at this location:

/home/pi/RetroPie/BIOS/amiga

With recent Amiberry versions the KickStart rom name doesn't matter as only the hash is being checked. Therefore I did rename my 3 KickStart roms as follows:

kick13.rom
kick20.rom
kick31.rom

I'm only relying on those 3 files as listed there (the ones with the little checkmark) with my roughly 800 games testbed on a stock RPi4. This without issues. Games are a mix of (mostly) Amiga 500/1200 as well as some Amiga CD and CD32. Amiberry for the RPi does come with an autoconfiguration file for majority of games which makes it almost console-like experience. Drop the KickStart roms in /home/pi/RetroPie/BIOS/amiga, drop the games *.lha in /home/pi/RetroPie/roms/amiga and you're all set.

I have to admit I never tried any libretro UAE core but I'm sure this works great too as per @jamrom2. Plus you have all the fancy stuff included with RetroArch.

Irrespective of the emulator you chose the most important is that it's really easy now for any users to enjoy the good old memories of Amiga on RPi!

Hope this helps.

@jamrom2 I use LR-PUAE on my PC and haven't had any problems.

@George-Spiggott who lot more horsepower under that hood than a Pi3b+. Lol.

Mopar big block to a Hyundai 4 cylinder. LOL.

@nemo93

Thanks for this Nemo. Seem as some of the cores get updated the BIOS files are moving into named folders.

@jamrom2 I had very few issues with having enough power on my Pi3B+. I think the A500 version of Seek & Destroy will run at full speed (and take up much less room), I'm not sure about Alien Breed 3D2. I think Jim Power was a little slow as well. We're talking about a handful of games out of hundreds that run slowly.

jamrom2

@George-Spiggott I agree. I normally have no issues running games.

Bonanza Bros dragged for me. Never got it right.

But other than that, 95% run full speed, or very close.

@George-Spiggott I switched up some of the games to the new Amiberry. Wow, it's a lot better now and very easy to use.

It's been a while since I used it, and the last time I had a lot of issues with controllers being properly recognized. Now, no interaction required. One-click, and I'm playing.

I also did some performance tests between the two with A-10 Tank Killer, Knights of the Sky, Bonanza Bros, and PowerMonger.

Nearly the same performance between the two, Bonanza Bros definitely ran a little better on Amiberry Angina 500+ setting.

But other than that, they're equal. That was with overlay and shaders active on lr-puae-2021.
