Tfx
Hi all,
I am trying to launch TFX for Amiga with the Amigaforever emulator but I receive this error message, can you help me please? "this program requires a math co-processor TFX failed returncode 20" |

If I recall correctly the game needed 8MB Chip RAM and an FPU to run smoothly on WinUAE. Others may know more about the FPU part.

2MB chip RAM should be enough - the rest of the RAM requirement is better off being fast RAM. It ran reasonably well on my A1200 with an 060 and lots of fast RAM... I would say just add the FPU to the WinUAE setup to get it to run, or else set the emulation to have a CPU with built-in FPU such as 68040 or 68060.

There is a game file for TFX which doesn't require an FPU, see here for details: TFX (Tactical Fighter Experiment)

How on earth would a game be written to use 8M chip ram when an 8M chip ram Amiga never existed? Was it really written in such a forward-thinking way that audiovisual elements would be cached in chip RAM so that a future 8M chip ram Amiga could benefit from them?
I doubt the game even uses much chip RAM at all, and just does most of its stuff with general purpose RAM, so 2M chip RAM 128M fast RAM would be fine. ...but in reference to the original poster. You need to enable an FPU to play it, as the game uses floating point math for accurate geometry and physics calculations. |

Must be something new about signatures. Apologies, thought it was only specific to the Tapatalk I had forgotten on the mobile, removed! Quote:
It wasn't. Yet, the game was never 100% complete as it was stated in that post, and several bugs were present. Anyway, here is the configuration I had read suggested for maximum playability on WinUAE: CPU:020 JIT (FPU Support, Constant Jump, Hard FLush, Direct, No Flags, Catch unexpected exceptions) MMU None Fastest Possible FPU 68882 AGA Immediate Blitter Collision Level Full RAM: 8 MB Chip only Cheers!

Regarding settings for TFX; I belive mine are as follows but will verify once home tonight:
... CPU: 68040 ... JIT ... FPU: 68882 ... No MMU ... Fastest Possible ... AGA ... RAM: 2MB Chip & 4MB Fast RAM or possibly 8MB Fast RAM |

Do you run on "Fastest possible"?

From memory, the cannon will not work in the FPU version. |

In general for best performance if you have to choose between something compiled for 68040/68060 FPU and 68882, pick 68882 as the workarounds for unimplemented instructions for 68040+ will run slower than just emulating the 68882 instructions.
On the other hand integer stuff for 68040+ will emulate the fastest if it uses MOVE16 a lot. |

Was there an Amiga version of TFX that had the full gouraud shading of the PC version? I think what's confusing me is that the advert for the Amiga version (which was on my wall for a while) had it in the screenshots, but I know that was a common marketing trick at the time.
Incidentally, the advert also mentioned a CD32 version, which obviously only had 2MB chip RAM and no fast RAM, how on earth would that have run? |
