I know several people have said that a 68000 is too slow to run WHDLoad


Tell those people to know what they're talking about. That's nonsense.
I use Whdload in my plain 68000 Minimig in 7Mhz mode (As I did in my A600) and 68000 games run at 68000 speed.
Whdload is NOT an emulator. If a game is slow on a plain 68000 then it's going to be the same if you run in from floppies or a clean Whdload install.

The ONLY exceptions are a few 68000 games wich have blitter waits inserted in their Whdload installs, wich allow the games to run at the right speed on higher-end machines (James Pond 1, for example). But if you're running those games on a plain 68000 then all you need to do is disable the blitter waits, and presto, you get the same speed on a 68000 as the game has in a... well, a 68000 :D

Thanks for the info man.  Thats good news.  This opens up a whole new world for me.  I do have one more question for you.  I'm thinking about installing it on my Amiga 1000.  It only has 512k chip ram and will have 8mb fast ram.  Will WHDLoad still work, or will I have too little chip ram?  Thanks.

You'll be short on chip for many games, as games that demanded 1MB chip RAM in the Amiga 500 period were quite a lot. When a game needs ChipRam, it NEEDS ChipRam. Even if you get 128MB of fastram, you'll have just 512KB of ChipRam :(

I don't know much about the Amiga 1000, never seen one in person, maybe it's possible to fit 1MB of ChipRam... Other people can help you better with that.

The other BIG problem I see is that kickstart ROM on an Amiga 1000 will be 1.x. That's bad because Whdload won't work unless you softload (softboot?) into a 2.x or 3.x kickstart. But I believe I read about you already doing so in some other thread!

This is kind of off topic, but would having Fast Ram installed on an Amiga 1000 make a difference in playing games off floppy disks?  Is the computer able to cache the game in memory resulting in smoother game play and less disk swaps?  Thanks.

Well, it's actually up to the game. I know MANY games will show nice screens saying "memory expansion in use!" or something similar, and you'll get a warm feeling, better graphics or more audio effects, etc... But I recall that happened most in the Amiga 500 days and I believe these games were really using my trapdoor chipram expansion (I've been using Whdload for so long I almost forgot those things). I hate floppies.

I've never turned off "turbo mode" on my Minimig.  :)

WHDLoad works like a charm off my ClassicWB HDF file.  It boots off a KS3.1 ROM and I have 1MB to Chip RAM and 2.5MB to Fast RAM.

I'd like to do the same, but TURBO mode breaks audio on many games, like Ishar, wich I play often. (Well, in-game sounds are there, but the AWESOME Conan-esque intro music has wrong timming in Turbo mode, and I always start a game getting into mood with that music).
