WHDload & Amiga-600 with 1MB expansion ?!?
Ok, I wanted to ask this for a long time:
Does it make sense to install a harddisk with WHDload games on an Amiga-600 with 1MB expansion in the trapdoor (in other words, an A-600 with 2MB chipram) ? Or does WHDload require more ram or other ram (fastram ? slowram?) If yes, which easy possibilities do I have to get that additional ram ? I don't think there are any pcmcia ram expansions easy to get, right ? Thanx for your help guys ! |

You can also try the russian 8MB memory expansion (EAB thread here) or wait for rkauer's accelerator |

You'd be surprised how little RAM you need to get some WHDload games working. 1Mbyte is kinda on the small side. I found that 2Mbytes was good enough for a lot of games, especially with an ultra slim startup sequence.

What about CPU? I've read so many references to how WHDLoad is better with an accelerator but nobody ever seems willing or able to say exactly why. Since most games are designed to run on a 68000, why would a faster CPU be of benefit?

Just about any games (as long as it's not AGA) on those CD32 WHDLoad compilation discs (CD32-200, CD32-444...) should work on a 2MB A600, but you'd have to make your own selector menu or run them from AmigaDOS (I think AGS is AGA only). These games usually need to be run with their own startup-sequence though, which AGS copies into RAD:, so if you could write your own scripts from Workbench that copies a startup-sequence for each game into RAD:, reboots, then runs the game.

Well, my A-600 currently has 2MB chip (1MB onboard and 1MB in the trapdoor).
So, I can assume all WHDload version of the games on the CD-32 cmpilation cds don't need more than 2MB, right ? But I cannot simply copy them to hd because the startups are missing, right ? hmm, that looks like a lot of work, but couldn't I simply take KG's WHDload versions of these games instead ? I don't need any menu, staring them from amidos is more than ok for me also, do any trapdoor expansion with more than 1MB exist ? I don't think so because trapdoor mem is always chipmem, and it cannot exceed 2MB in total because of the 8375 Agnus, right ? |

I've only seen it on one or two titles, ususally only on the intro screen where they are using all the CPU horsepower to make a pretty attract screen. Quote:

Often the 68000 games/demos use SMC (self-modifying code) and/or don't wait for the blitter to finish. This needs to be fixed for 020+ CPU's and thus requires extra code which often will slow down the demo/game.

But of course some forward thinking WHDLoad installers have made parts of the patching optional with a CUSTOM tooltype to keep the best possible speed on 68000 systems.
No idea who that was though... |

Chances are that I am using the original WHDload slaves and not the most recent version of WHDload. I would also check your tool types for each slave. |

In my opinion, isn't worth the hassle and with a 2MB SRAM card I don't have to worry about memory issues anymore. |

several installs have no working quitkey on a 68000 because they assume the automatic quitkey feature by WHDLoad itself which is only available on a 68010+

Although the present cpu can be checked by the slave and therefore it is possible to avoid these patches on a 68000

But there is the case of fast 68000 boards - like Adspeed or Supra28. Although the SMC might not matter so much the blitter waits could be important.

Hmm, yes correct. In case of a very fast 68000 this can be unreliable.
My approach would be that the install should work on every setup without setting any Tooltypes/options. The best is then maybe a automation via the cpu detection, with the possebilty to overwrite this with a Custom option. |
