I finally got it up and running, I jumped the gun before your post but thanks so much for the help.
Basically, I added the 4 ROMs you said and named them accordingly, but, I also had to copy the kickstart 1.3 ROM and name it simply kick.rom and everything works great.
One last question, Is there any downside to cranking all the memory options and floppy speed options as high as possible?
Thanks again :-)
Don't touch things like Chipmem nor Slowmem except rare cases (1MB is fine for almost everything, old games might require 512KB+512KB Slow/Bogo Mem). If you feel like trying something powerful, go for 2MB Chip.
Most expanded Miggys had that much back then, and a lot of games use the additional memory for added things (see below).
You can add up to 8MB of Fast memory, which some games will use for speeding up loading times, additional gfx/sfx and other things. It's usually safe to keep them set on all the time, as it doesn't interfere much with the Amiga itself. SOME games might do funny stuff if it's on, so if a game doesn't run, try turning it off.
As for floppy speed, usually when you set 800%, you're asking for trouble. Most games with special loading techniques will fail, you'll experience resets and black screen often, and all that jazz.
If it has got a "Turbo" option, that's the best choice. It should speed it up massively, without breaking compatibility too much. 200% is also a good value (sometimes more compatible than Turbo).
As a rule of thumb: If something doesn't work, turn back to STOCK configuration (A500, A600, A1200) and see if it runs. VERY old games (85-87) might require an Amiga 1000. Every OCS games usually runs on Amiga 500 (the most compatible of 'em all), and AGA games require you A1200 (if the AGA chipset IS supported, I dunno about that). A600 is good for games that require Chipmem 1MB or Kick 2.05. But most games also run on A500 - only funny cracktros and wrong cracks might require you an A600. Or a game that specially uses ECS (they're rare).
That's it, I guess
