Doesn't go blank if "video timings" are set to Pentagon, but the timings are not correct then for the multicolor effects. The demo is written for ZX Spectrum 128k and I've tested it on +2 and +2A. It works well on V6Z80P also.

Many demos were created for popular Russian Spectrum clone "Pentagon 128".
This clone has different display/INT timings than original Spectrum's ULA chip.

Need to make OSD switch for Original/Pentagon timings if enough info will be found.

I'm unable to read any TRD file that I create with Fuse's scl2trd utility on the MiST using the Spectrum core.

If I go to TR-DOS and try to CAT the disk, it hangs forever.

I've tried this with multiple images, for example: http://trd.speccy.cz/gamez/d/DDAR_POS.ZIP

The same TRD file works correctly in the Fuse emulator.

Hi,
for the MiSTer there is a simple fix for mister.ini . Can the problem be solved on the MiST as well?

This demo http://www.worldofspectrum.org/infoseekid.cgi?id=0007386
Doesn't go further after titles.

The problem is not in CPU module. With T80 CPU it stuck at the same point.

There is no picture displayed (out of range). Tried three monitors (Vivitron CRT, Syncmaster 192v and TV with VGA). All other MIST cores are working. Old spectrum cores are also working. There is scandoubler_disable=0 in mist.ini.

Hi,
ESXDOS with browser is very important for me (.TRD support). I added ESXDOS V0.8.8 (BIN+SYS folder) according to the instructions, and it works. However, when I do a hard reset and reload the zx_spectrum_128K - core, ESXDOS is not reloaded. The MNI browser remains off. If I turn off MiST for a minute and restart the core, ESXDOS starts up again and works normally again. This is weird behavior, why do I have to turn off MiST for a minute to allow ESXDOS to load again?

Best regards,
MiC

Ninjarjar! game from Mojon Twins, don't start when the load finish. I try serveral version with the same result.
Thanks.

I noticed the enable register of the YM2149 chip is reset to all "1":

But according to the datasheet, RESET should puts all registers to "0":

Is there any specific reason why this behaves differently from the real chip?

Version 221024, but checked some older and seems to be the same.

The joysticks seems to not map correctly to its corresponding Spectrum controls.

In all the cases is the same, the up and down directions are not mapped to its corresponding ones and makes random behaviors depending the game, some move to left when pressing down, others pauses the game, etc.

The only combo that makes joystick to map correctly is when attaching an USB controller and a DB9 to the "natural" second DB9 port (the one that core assigns to joystick 2 if no USB is attached). Then only the DB9 one is mapped correctly to Spectrum controls.

We can easily check this selecting Sinclair I and II, the first is mapped to keys 6-0 and the second to 1-5, so launching i.e. +3 BASIC and moving the stick should write the numbers. And as I say it only does from the DB9 one when connecting a USB. By this way all the issues mentioned like characters doing weird things or pausing go off and the control work nicely.

If we connect 2 USB so they are joystick 1 and 2 can check that both are not mapped correctly, no one writes when pressing up or down.
