Yeah, I think that's the person I was thinking of. Thanks for finding it!

Does that mean that in older Amigas there no way past a 512KB limit?

A500 and A2000 are easy.

A1000 is just as easy to convert to a 42pin rom as it is a 40pin rom, >256mb of WOM is hard.
 
A600 and up support 1mb roms

To make your own:

There were tries in the past from some guys like ROMflash that sadly never made it in the open.
I found that making your own custom kickstart is cool. If you map it via MapROM (like ACA cards) or in FPGA Arcade is better and full of win


Ah, thanks mfilos! This is pretty much what I been think of.

AROS m68k ROM + AROS Wanderer = Complete open source solution for Amiga?

Does it work?

Game compability?

There is plenty of proof out there that it works. Best way to test it for yourself is by running a nightly build of AROS 68k in WinUAE.

Game compatibility is a tricky point to address, as the AROS ROM is improved almost daily at the moment. Let me point you to a comment made by gilgamesh over at AROS-Exec:

I hope that answers your question. ;-)

Is it the AROS-20110331-amiga-m68k-system/boot/aros.elf 1081644 bytes long that is the ROM image needed?

"file:"
AROS-20110331-amiga-m68k-system/boot/aros.elf: ELF 32-bit MSB relocatable, Motorola 68000, version 1 (SYSV), not stripped

The files you are looking for are in AROS-20110331-amiga-m68k-system/distfiles/

Since you are talking of customized roms, I may point you to this page I created with information on custom rom modules to include in your kickstarts:

http://lilliput.amiga-projects.net/ROM_modules.htm

I hope you find it usefull :)

The ROM is the first 512K, the EXT is the "extended rom" which is the 2nd 512K.

The CD32 always used 2 roms.

You'll notice in WinUAE you can map a 2nd "extended" rom file.

I didn't know that. Will WinUAE only map a second extended ROM only with 512MB ROMs or will it accept larger ones?

WinUAE can map Normal + Extended ROMs, or also Large ROMS like 1MB custom ROMS.

For example if you make an 1MB custom kickstart image, you can either map it as Normal and Extended ROM under WinUAE, or Append the Normal+Extended into a big 1MB ROM image and then:
- Mount it in WinUAE as a big Normal ROM
- Kick it via MapROM using an ACA accelerator
- Burn it in an Eprom Programer (after ByteSwaping the image).

Can these AROS 2x 512 kB ROMs be used on an Amiga 500 ?

Considering it only has a 256 kB ROM from start.

Also does Wanderer work alright? (not perfect)

I don't think AROS works on an A500 at the moment, don't think there's a graphics driver for OCS (yet). It does work on real hardware though, as shown in this blog entry showing AROS running on an A1200:

A500 rev 6+ support 512k roms, earlier versions require a wire added between 1 & 31. To support 1mb roms you need to run some wires to the extra pins on the rom (the socket is 40 pins but a 1mb rom is 42 pins).
