A500 ROM upgrade questions...

There are absolutely NO advantages what so ever if you do not have a hard drive.

In fact just the opposite! As soon as you "upgrade" to KS2.04+ close to a quarter of the floppy disk games you have will stop working due to their reliance on KS1.3

As for "OS3.1 ROM allows you to upgrade to OS3.9" you should forget it. You'll not be using that on an A500. (Uneconomically viable)

To quote a well known saying : "The best upgrade for an A500 is an A1200"

Gonna look up for some ROMs and ROM switcher then!

What for? You dont need updated ROMs!! Not unless you have a hard drive. And if you have a hard drive, you dont need a ROM switcher cos you can use WHDLoad.

If you cannot get a A590 / GVP HD8+ SCSI hard drive then why not try to get a IDE68k (Although I would try and wait for the version with RAM)

And you want rom 1.3 for games like Uridium, Gauntlet 2 etc.

If you've got a hard drive (preferably one with a few MB of FastRAM) and KS3.1 you don't need a 1.3 ROM or a kickstart switcher to play these games, you can use WHDload and play the games from HDD as I said.

Without some fast RAM WHDload will not work, not even a single game .slave that I know uses only chip RAM.

Just not true. Lots of slaves work with only 1MB or 2MB of ChipRAM. (Preload often wont work, but the game will run without it)

How do you think the CD32 WHDload CD's work? They do not have any fast RAM.

Or on A600's? The majority of those also have no fast RAM.

I had some problems with KS3.1 in A500, but there is a solution on EAB forum. You might need to put some missing resistor packs near CPU slot.

Oh yeah and I forgot to mention, depending on which A500 motherboard you have you cannot use a 512Kbyte Kickstart ROM (like KS3.1) without some soldering and rewiring of ROM pins.
