whdload compatibility

Vasek · 04 February 2004, 20:46

Is there any chance to update whdload compability? some games like Xenon II runs on regular amiga with whdload fine. But under winuae is´t working.

First, "isn't working" isn't very good bug report..

Unfortunately there isn't any easy fix.

IMHO, I would even say Whdload game that does not work because of WinUAE's "too" fast CPU or chip RAM access speed in JIT mode is buggy...

WinUAE in JIT mode won't ever have compatible (=slow) chip ram access speed which is the usual reason causing problems with games.

Ticking "cycle exact"-checkbox may help (but note that it only does only affect blitter speed in non-68000 modes)

It probably does work, just try playing with the settings (Processor, RAM, etc) and see if you can get it working that way, as I doubt it is a WinUAE problem (can't find a single game that I can't get working without tweaking now).

thanx for answer

I just asked because Xenon2 is 1 of about 500 whdload games which is not working under WinUAE on my config.

Vasek · 05 February 2004, 22:31

I have add taht i have 3 XenonII version. One is with JST patch which is wotking till title music than it crashes to guru meditation. Other 2 are Whdload - CDTV version is working, but there is no music

(it use audio tracks on cd) and the other one is 2 floppy version which shows something like "illegal instruction" ....

(sorry for my englis

)
WinUAE is great great great .....

I haven't been able to get the floppy version of Xenon II to work with WHDload/WinUAE either. The CDTV version works like a charm, but the floppy version is completely impossible. Now, I have tried messing around with the settings a LOT but it just won't work (haven't tried this latest version of WinUAE though). Overall the results for me have been the same as for Vasek. Illegal instruction with WHDload, and guru for JST.

The illegal instruction could be because it crashes on the copylock checks - so the version used by you is probably different to the version that WHDLoad expects.

Mine works on WinUAE 0.8.22 release 6
Config: ECS agnus, 2Meg chip, Kick2.0, 68000 (match A500)(more compatible), Sound enabled

Whdload version 14.5 PRELOAD NOVBRMOVE (although I don't think these matter)

Slave: Xenon 2 - Megablast installed & fixed by Wepl Version 1.6 Floppy (16.08.2000)

BACK TO THE ROOTS is a good website for tested & working WinUAE configs.

Toni Wilen · 06 February 2004, 11:32

But running WHDLoad games should not need any special A500-compatible configs...

Vasek · 06 February 2004, 18:58

The same config is working on regular Amiga ...

Toni Wilen · 06 February 2004, 23:32

Xenon2 expects CPU instruction prefetch. UAE don't bother to emulate prefetch if selected CPU is 68010 or higher. (and it would be nearly impossible in JIT modes)

Adding simple prefetch emulation to non-JIT 68020-mode would be quite easily implemented.

; here we overwrite next instruction with 0x4afc (illegal instruction)

For some reason, whenever I try to run half my whdload games from WinUAE 8.23, it will crash out of WinUAE completely. No error messages, it just kicks me to windows and the program is gone.

I have problems with chipset: cycle exact CPU & blitter when running hybris with whdload 16.1 and latest winuae 0.8.24, see attached picture, left with fast copper and immediate blitter ticked and right with cycle exact cpu and blitter.

zerohero · 07 February 2004, 18:48

The config i use for my previous post is attached below... another
problem i have with this config is that if i select chipset: cycle exact cpu and blitter and starts winuae with this configuration and press F12 to check the chipset tab, no selection is made..?

so i have to bootup with fast copper and immediate blitter, change settings to cycle exact and reboot, voila.... correct settings
