"This is a software driver for Warp3D, which enables:
using Warp3D applications, demos and games with PPC Amigas not equipped with a 3D GFx board, or not equiped with a GFx board at all (but requires P96 or CGX) [and] using Warp3D applications, demos and games not compatible with a 3D Gfx board (example : WipeOut and CGx4/Voodoo3)." More details in the readme.

Warp3D software render driver : Comment 31 of 158 | ANN.lu |

Then your tester should know that actual emulation issues should be addressed to Bernd Meyer at bernie@amithlon.net, complete with details of the problem. It is Bernie who deals with the actual emulation engine, and if it crashes on Amithlon but not on XL or real Amigas there can only be two explanations:
(a) There is a bug in the JIT optimisations done on Amithlon which are missing from XL. This can be checked by switching off the JIT in Amithlon - it will run too slow to be really useful this way, but it is a good way to isolate JIT issues.
(b) Quake2 makes some call to the custom Amiga chipset which is emulated under XL but missing in Amithlon, which has no chipset emulation to speak of. As you mention that the problem results when using a particular compiler setting, this probably eliminates this possibility.

Sigh. Ask your tester, and he should be able to explain. If I am forced to exit Amithlon and reboot to play Quake 2, why would I choose to boot into QNX and AmigaXL to run a software rendered Q2, when I could boot into Windows or Linux and run a fully 3D accelerated port of the game. Besides, not all Amithlon users bother installing QNX and AmigaXL as well.
> I did not test on WinUAE, BTW, so I do not know if it runs there.
It may be interesting to check. The WinUAE JIT engine is somewhere between the AmigaXL one - which is slower but more stable - and the Amithlon one, which is faster but also has lots of extra optimisations where new bugs may hide.

Nobody is flaming you for doing a 68k version. However, if I found a bug in your software you'd expect me to report it to you, with details of how it happened. If I reported it to Ben instead, you might not get to hear about it for some time. See? |
