[Solved] MiST Hardware Revisions? MSX-Core-Problem

[desUBIKado]

I hurried a bit. It seems that the RGB output is slightly displaced to the right.

For me screen is centered but it has darker colours I can confirm that. I am using a 15khz CRT TV.
Problems so far:
- First boot MSX detects only 2048kb and does not load MSX DOS. After a reset it works
- Most of the times after MSX DOS loaded there is a "Enter" key repeat until I press "Enter" again. That happened on old core
- Darker colours

I don't know if it is possible to run games in CAS (cassette) format.

[DanyPPC]

Yes, you can run Cas games by using SofaRun which support most games.

The original core has a weird reset circuit with a tons of latches and async loops, which makes it a bit unpredictable to work. Once I have to clean them.

It happens only when you have saved the msx.vhd on a SDCard just full of other cores and relative games.
On a new formatted SD Card with only MSX Core this not happens.

On Kdl Twitter page I read this:

So could there be a switch inside the source to switch between these 2 modes to adapt to the screen in use?

[slingshot]

I think these modes can be cycled with the PrtScrn key.

[DanyPPC]

YES, you are right !!!

My screen is now centerd and in full colors !
Only a bit dark as luminance/contrast.

Good! MiST framework has a single scandoubled/non-scandoubled switch, maybe there can be an OSD option to select from the two scandoubled modes. Or just leave PrtScr as an override for the switch.

[DanyPPC]

In the old core there is that option on the menu, and it can be saved.
Would you be able to improve brightness and contrast ?

[vebxenon]

No problem, i will upload a basic vhd for the new core.

In the meanwhile i tested the standard 2 button joystick on DB9 ports and i confirm there is no support for the secondo button in this core.

I don't know why there is this bug with some ghost keys, even if i don't connect the keyboard.

here the MSXVHD file

Sometimes you need to reset the core.
A long press of the Reset Button (first from the right) acts as a cold reboot. Useful to discard roms from the memory.

Hi! It's possible to make bigger the VHD? I've created a 256 MB VHD and I'm not able to boot the core , even I'm putting first the bios and I've dumped my 1chipMSX card.

[DanyPPC]

What size do you prefer?

[slingshot]

Added the DIP switch option for VGA Output to the OSD (and fixed YPbPr output):
https://github.com/gyurco/MSX_MiST/releases/tag/1.3

About brightness and contrast: KdL's core output is 3x6 bits, so it is directly sent to the VGA output of MiST. No change happen to the signals in RGB mode.
PS: I could use an 512 MB VHD with a BIOS set-up for a B: drive.

[DanyPPC]

Thanks Slingshot, now I test it.

With new 2018.11.21 version of the core this problem is fixed. Thank you.

[vebxenon]

What size do you prefer?

If it's possible, 256 or even better 512 MB, as I have in my 1chipMSX card and in my Megaflashrom.

Thanks!

That's a good idea!

OK, 512MB

Thanks very much!!!

Ahh, thanks, I'll search for MSX2PLUS.

It's a pain to use ESET every time to add a new drive letter, is there a command line version of it, so I can put it to autoexec.bat? (otherwise I can just instantly reboot with the new disk, cannot use together with existing A: drive).

on OLD Core i simply go to msxdos and digit:

> EP GAMENAME.DSK B:
> B:
B:\>BASIC

In the basic i digit:

FILES

to see the directory of disk, load AUTOEXEC.BAS to modify as already mentioned.

In this new core I don't know why this simply metod doesn't work anymore.

On the net there is an AUFMONTY patched ROM which I usually Load with EXECROM. For EXECROM you have to set MegaRam on the First Slot (Old MSX CORE), the sintax to load the rom is:

EXECROM /R2 AUFMONTY

so you can play this game on MSX2Plus and OCM.

On the new core I cannot use EXECROM.

Hello guys. My name is Rubem And I am new in this list. I just using the new msx mist core and I am facing the same problem EP xxx.dsk b: is not working anymore and I don't know how to use the command ESET. I tried without success. Does someone can help me to use ESET to add a new drive letter. when exit the ESET. I have the message "not ready reading drive A" "Abort or Retry (A/R) ?" Should I do something before using ESET ?

Thanks

Took a break from fpgagen development, so written a MiST top-level for KdL's OneChipMSX release (the same Sorgelig used for MiSTer):

https://github.com/gyurco/MSX_MiST

Need an SD-card with FAT16 formatting, and the first file must be the OCM-BIOS.DAT file. I found the BIOS loader very picky about the formatting, I could use only a card formatted in Win7 successfully. Here's the original website with sdcreate and MSX-DOS:

https://gnogni.altervista.org/

After you created and tested the SD-Card, you can copy it to a msx.vhd file, and put on your regular MiST SD-Card.

I have a problem with this core:

My MIST is updated with the latest firmware "firmware_181013.upg"; Interestingly, the OSD shows me "ATH181006" ... is this correct?

The problem is that I can not boot the msx core:

  - I have used SD of 1GB formatted in fat16, another SD of 16GB with several cores with fat32.
- I have also tried using only the BIOS file and the core.rbf (boot and jump to the basic?).
- The method using a VHD image does not help either.

It seems to me that the MIST is the model of 2015, could that be the problem?

The only thing I see in the CRT is a brown background and pressing F12 shows the OSD correctly, but even if I change something and save the changes it still does not work.

Excuse my English, I use a translator.

With last Slingshot Core release you don't need a limited 1GB / 2GB card.
Use a standard SD FAT32 formatted Card, copy in MSX core, MSX VHD posted in this topic.
Don't forget your standard MIST.INI file.

Yes, I built it on 6th, but just uploaded on 13th. Did other things between them

- I have also tried using only the BIOS file and the core.rbf (boot and jump to the basic?).

If it loads the BIOS, then at least the boot loader could read the FAT. If it goes only to BASIC, press reset, it should load MSX-DOS (pretend it is copied to the FAT fs). KdL said it is even happening on the original OCM. If it doesn't even load the BIOS, there can be other problems, which I think fixed recently, just didn't make a new release yet.

Well, I formatted an SD and copied both files (core.rbf, msx.vhd, mist.ini).

At first it shows the screen with the background in brown as before, but ... after pressing the reset button several seconds the msx3 logo appears, thank you very much, I missed the detail of the reset.

[DanyPPC]

Sorry, I forgot to mention the "reset" story.
