thanks for the videos! looks good. And the cache isn't working yet so it could be even better.
About SMC here game changes some areas of the code not directly after the SMC code (which explains why 68020 might not experience issues as the cache is small). It sets 3 or 4 instructions with either OR or AND for instance, depending on the draw phase (mask or draw). Not something you can do with more registers, but more with jump indirections and function pointers doing an indirection in a loop wastes cycles, but wrapping the whole loop in the routine makes the indirection cheap and that should be the solution. |

thanks. I'd say that 100MHz is just too much for your 060 I don't see why it would crash like that (illegal instruction in a random zone) with 100MHz and work with 50 MHz.
From what I saw it's pretty much playable now. The low framerate was the blocker. |

Alpha 2 test on my A1200 with TF1230 50mhz. Seems stable enough so far.
I haven’t tried it on my A600 with Furia yet but I’ll try shortly and post the result. [ Show youtube player ] |

This can also probably be reproduced with FPGA and PiStorm accelerators. |

Just realised I didn’t try to run the game with “run with rebuilt fast exe” ticked. When I tick that box I get this error on both my A1200 withTF1230 and A600 with Furia.
EDIT: ok adding MMU to the tooltypes got it running on the A1200 but it wont work on the A600 furia as that doesn't have an MMU. Last edited by Superman; 10 May 2022 at 13:30. |

this is a beta version, I'll remove the protectread calll which is a debug function and it will work on your furia.

Disabling the caches will probably make the game slower. Or ... running the original exe lol. |

Just to clarify the framerate doesn't increase at 100mhz, but the game timer does, making the game uncontrollable and unstable. It's weird because on WinUAE it's running normal speed even with JIT.

I had some issues with the new build, Jean François. I could not get it to load at all. I tried various parameters as well as using none at all. I have posted a Coredump in the (red) Zone. :-)

From what I see in the coredump file you forgot to enable "fast executable" in the options this time.
There's a bug, for only people who select original game with crap framerate. If it's not that, try with NOCACHE again. Last edited by jotd; 10 May 2022 at 22:51. |

Is the original especially rare? £160 and £130 in Ebay (although from same seller)

I bought an NTSC version on import around 2002 from SoftHut. I don't think it was expensive. Under £36 inc postage (I wouldn't have bought for more because it would have triggered import duties). I bought it not because I particularly wanted the game but at the time it had never been dumped for SoftPres (then CAPS). Also I don't think people at the time believed an NTSC version existed. Even now, 18 years after I did the dump, I don't think there is an official IPF. The feedback from SoftPres was "all RedZone disks had a manufacturing flaw. Even NTSC ones." https://eab.abime.net/showthread.php...977#post174977 I'd be interested in knowing what the "Manufacturing error/flaw" was and what it means for the game?
