Curious about a A500/600 rom forsale

[mrbill317]

It says its unofficial and its 3.5 rom

Was there really a hacked rom that version?

What does it do or give my Amiga 600 or 500+?

Thanks guys

His info says that it allows 3.1 or 3.9 on a 500 or 600

I expect he took a 3.1 ROM image patched with the 3.5 updates and burned it with an Eprom burner.  There's a 3.9 ROM image too that some Polish guy burned to a ROM and put in his A1000.  On an A500 or A600, a A 3.0 ROM will allow AmigaOS 3.1, and a 3.1 ROM will allow 3.1 + 3.5 + 3.9.
