[Ghost key bug]

If you use the Core on an new formatted SD card as a single core for this card the problem of the "ghost" keys does not manifest.
If you use the Core on an SD card already full of other cores and roms then the bug shows up.

In my case the ghost key is "6" but sometimes is "2".
Obviously on the MSX-Dos shell.

It's a pretty boring bug.
With the previous Core instead there was only the Return that was pressed to not have the "ghost" pressure of the same at boot.

I did some modifications to the PS2 controller, I don't experience sticky keys anymore:

Great work that is being done with this Core, but I still notice a big difference in the brightness and vividness in the colors compared to the old and first core of Msx for the Mist, I attached some photos with the different cores to compare, they are made in the same moneto and in the same light conditions.

Luminance fixed, now you have 100% luminance. In emsx_top.vhd file has the problem.

if( ZemmixNeo = '1')then -- Luminance 100%
pDac_VR <= VideoR;
pDac_VG <= VideoG;
pDac_VB <= VideoB;
else -- Luminance 56.25% = 50% + 6.25%
pDac_VR <= ("0" & VideoR( 5 downto 1 )) + ("0000" & VideoR( 5 downto 4 ));
pDac_VG <= ("0" & VideoG( 5 downto 1 )) + ("0000" & VideoG( 5 downto 4 ));
pDac_VB <= ("0" & VideoB( 5 downto 1 )) + ("0000" & VideoB( 5 downto 4 ));

You need to force ZemmixNeo mode.

Great, I wonder why darkening is needed on the OCM. Maybe something strange in the output DAC.

Hello,
audio output volume of MSX core is very very low, this new core is lower than previous core that i've used until now (last core with FAT16 and 2GB limit)
is possible to fix this issue please?

Hello again,
new core is very good but 512MB VHD file it's too small for me.

With previous core (that with fat16 and 2gb limit that not use VHD files i mean) i could use entire 2gb for games..

i would like to have a 3,9 GB VHD, for going over 2GB FAT16 limit and because i've a lot of MSX1 & MSX2
ROMs and DSKs files (actually i am using a FAT16 2gb SD only for MSX1 games and another FAT16 2gb SD
only for MSX2 games)

I've tried to resize 512mb partition with "VHD Resizer" program and i've got a new 3,9GB file but only first 512mb are used and rest is blank space

Then i've tried to create a new 3,9gb VHD file (with Windows 10) and copied all datas from your 512mb VHD
file into this new 3,9gb VHD file but then MSX core won't boot.

May you help me to get a 3,9GB VHD working file please? (3,9GB and not 4GB because 4GB won't fit in a FAT32 SD)

Thank you in advance

EDIT : i am trying to create a single MSX.VHD 3,9GB file with inside it, 2 FAT16 2GB partitions, maybe this may works

There are three volume types, OPLL, SCC-I and PSG. The volume control is in middle position, you can use keys control volume.

F9 - Up PSG
Shift F9 - Down PSG

F10 - Up SCC-I
Shift + F10 - Down SCC-I

F11 - Up OPLL
Shift F11 - Down OPLL

And Page UP - Page Down is for master volume, but master can not exceed the maximum established with F8, F9 and F10

Wow Thank you!

I will try them ASAP ^_^

For VHD,now i am trying with a single file 2 GB FAT 16 partition

Probably you can do a 2nd partition (and a 3rd one) then. I've also tried a FAT resizer in the past, but the BIOS loader is very picky about the filesystem, and refused to boot the machine anymore.

Tested the new option for mouse support and it works very well in the following games:

- Operation Wolf (ToyBox 2006) Remake
- Breaker 2 (MSX2) Disk
- Ark-a-Noah (MSX2) Disk

Thanks Slingshot :cheers:

They're 8 state switches, would be ugly on the OSD. And those switches are not exposed even in the original OCM to the outside world.

Btw, the volume controls are soft switches, so I'm sure there's a command which you can insert into autoexec.bat to set them at boot.

I've did some tries but no lucky.. Last one has been a single FAT16 2gb partiition VHD file created on a 4GB fat32 SD but no works..

I am stuck still on 512 mb only.. ATM prefer to use old core on 2 fat16 2gb SDs (1 for MSX1 games and second one for MSX2 games) but hope in a solution for using VHD related core instead

If you already have a working SD-Card, you can copy it to a vhd file, e.g. in Linux dd if=/dev/sdx of=/some/path/msx.vhd, where /dev/sdx is your sd card. The main difference between the old and new core is the BIOS file loading, the OCM loader is not very tolerant about the details of the FAT fs. You can try to format a card in Windows, copy the BIOS (first) then MSX-DOS and msx.rbf, if it works, you can make an image of it.

I will try this way too, thanks!
just a question, how has been created 512mb VHD file? Like you written in this comment?

I mean , in this way "copy the BIOS (first) then MSX-DOS and msx.rbf, if it works, you can make an image of it" ??

The 512 MB file was not done by me, but I've created on a 2GB SD-Card the same way. RBF is only needed because if you're using a physical card, then the MiST firmware must load the core from somewhere, in a .vhd file, it's not needed.

For creating an image of an SD-Card I usually use Win32DiskImager, but this in case of an amiga SD-Card image backup.
Never tested for an SD FAT 2GB card.
Win32DiskImager creates images in IMG format, I don't know if renaming it in msx.vhd then it works with MSX-Core.

Need to try.

I've tried to raise all volumes but it doesn't go up if i lower at zero, he become muted, but when raise it again, doesn't go beyond original very low level..

F9, F10, F11 and PG UP, i've raised all them
