Can AmiMasterGear, etc run on A4000?

[adolescent]

AmiMasterGear runs fine here on my A4000 with CSMK3.

Have you tried setting speed to Fast (instead of Real)?

A4000/2M Chip/CSKM3 060/50MHz w/128M RAM running in a normal AGA NTSC screen (no promotion).

AmiMasterGear Emulator v0.82 (23.7.02) (w/free keyfile)

Emulation Speed:
  V.Lines: 313
  Speed: Fast

Screen Options:
  NTSC (60Hz)
  SPR Refresh: 1 Frame
  GFX Refresh: 1 Frame

Options:
  Black Border
  No illogical moves
  Show fps (for this exercise)

  Video Emulation:
    Realtime Scroll Refresh

---

Things run at between 60-70FPS (usually 70) using these settings.  Changing speed to Turbo or Real makes it go 250+ FPS.  Changing the refresh to auto makes it go faster too.  (PAL works fine also, but my TFT complains so I use NTSC)

I'll load up AmiMSX if I can find a copy and try it out too.

Caches are all turned on by SETPATCH.  I think my RAM timing is set to 60ns.  I have no RAM on the motherboard right now.

@AMIGAZ

Do you have it set for CD32 pad and correct port?  I use one and it works fine.  The start button is supposed to return you to the menu.

@AMIGAZ

Must be some incompatibility in your system.  Download the source code and start debugging.

Mine seems to jump around at the beginning, but once in the game it's pretty consistent.  In Sonic the Hedgehog (SMS) it hangs out right at 70-71.

You could try degrading the system a bit before running the emulator.  Turning off CPU caches would definately make it slower.

AmiMSX seems to run only a bit fast without any changes (just setting the frame from 2 to 1).  There is no FPS counter so it's hard to say if it is running too fast.

I didn't notice any speed decrease with setting this, but it does improve the accuracy.  Especially the sprite and background priorities.

BTW, turning off caches makes it too slow.  :lol:  Edit: I guess you already said that.

Source is available, but IIRC not the last updated version.

yeah keropi that is a good idea but who could do it?! i think these emus are written in an easy programming language so it shouldn't be too hard for an experienced amigan. the sources are on aminet.

I don't think assembler qualifies as "easy".   :-)
