A500 512KB Chip VS A500 1MB Chip

[Lord Aga]

Are there any compatibility issues ?
Are there some games which would expect 512KB Chip RAM and then crash if they find 1MB Chip RAM ?

Both machines would have 8MB of fast RAM.

Not sure if I follow...
I have a classic 512KB Chip RAM A500 (+512 Fast, but that's irrelevant). Now I have the opportunity to exchange the 512KB Agnus with a 1MB one.
Would that change somehow cause some incompatibility ? Is there a piece of software that is 512KB Chip RAM specific, and would crash if it finds 1MB of Chip RAM ? Or is that impossible ?

Mhm, so this "IC 8372A, 1MB Agnus" isn't actually a 1MB upgrade. It is just a chip with a possibility to adress 1MB which must be obtained through further modification

@utri007
I don't have the 8MB fast yet. I was planning on buying kipper2k's 8MB fast + IDE combo upgrade for this A500.
But maybe I should leave this A500 intact for super compatibility, and just get an A500+ for whdload, as it was my plan all along

[Lord Aga]

Yup, everything perfectly clear now. Thank you
I don't think I'll be doing this. I'll go for an A500+ instead.
