Graphical errors in Amiga 500 .exe roms

[Dragon Mech]

i downloaded Arkanoid_-_Revenge_of_Doh_(1988)(Imagine)[cr_Trilogy].exe and Battleships_(1987)(Elite)[cr_Movers].exe and placed them in a folder that i mounted in the emulator (i'm using WINUAE v2.0.1).
as far as executing the programs, they work just fine. but when playing them i noticed some graphical errors in both games. here are some screenshots of the errors.

here is the battle screen from Battleships_(1987)(Elite)[cr_Movers].exe

and here are the screenshots from Arkanoid_-_Revenge_of_Doh_(1988)(Imagine)[cr_Trilogy].exe

when i play games from .adf disk images file they work fine. i've tried changing the video setting in the emulator but all that did was to slow down the emulator to a crawl. here are the specs of my machine

I am not sure why but I always use the ADF images.

Maybe you should try upgrading to WINUAE 2.5.1? Unless WINUAE 2.0.1 is the highest you can go on your system? Or maybe install fs-uae which focuses on emulating Amiga games using the accurate emulation code from WinUAE.

thanks everyone for your advice. version 2.0.1 is the latest version that windows 2000 can run. any newer versions require winXP or higher. i did manage to get the games to work by emulating an A3000 machine. but my real computer is having a tough time emulating the A500. logic would suggest that if i am having this much trouble running winuae, i would have just as much trouble (if not more) with FS-UAE.
