MiSTer FPGA Forum

Hi. I'm fine. The Russian occupiers have turned off our Internet and mobile communications. There is a slow Internet connection, but this one is not always available. Twitter and Facebook are blocked, so I'm writing here. I'm working on Saturn and other cores. Maybe not so fast, but I continue to work. Thank you all for support. Stay strong brothe...

Looks great on my CRT now, hard to believe that this is not even an official release now!

So yes, this single core has issues.

You can work around with tweaks or wait until it's fixed.

OK, so the core itself is the issue, good to know, guess I'll wait for it to be fixed.

Cheers

Sync issue with a single core?

caad wrote: ↑Sun Jan 23, 2022 6:42 pm Must be something wrong with your setup. Perhaps the YPbPr conversion.

Everything works perfectly with the other cores I play: SNES/SFC, NES/Famicom, Genesis/Mega Drive, SEGA CD/Mega CD, PC-Engine/PC-Engine CD, GameBoy/GameBoy Color, GBA, GameGear/SMS, WonderSwan. Only PSX gives me this issue:

Everytime there's a black background (Castlevania Chronicles for example), the picture is always moving in waves from up to down. 20" consumer grade CRT TV with YPbPr connection.

I have both of them and they both of them work on my NES, but only the gray one works with my SNAC adapter on my MiSTer.

This thread has some good info and links.

Ah, OK, found out the problem to everything, I was 1 MiSTer unstable core behind.

Cheers

Great, now nothing is loading, stuck in the BIOS. Anything major changed that I should be aware of (besides the fact that it allows me to load CUE files now)?

What is it that does not work? There might be a few games that still do not work with memory cards for this core. Does it just not work overall? The core got renamed to PSX, which means if you are using a Playstation folder for games and the boot.rom the folder needs to be renamed to PSX instead.

I get the latest PS1 and MiSTer unstable builds, downloaded the dummy memory card and set them in the core menu, but it doesn't work. What am I doing wrong?

Wonder why he decided to take this route?

The current serial functionality is a quirk to get 2 cores connected with 1 of the 5 connection mode, either as dual-core (splitscreen, dual screen) or even via multiple MiSTer if someone wants to build that. It's not working with a real (active) GBA connection cable most likely. As I have no GBA, no Gamecube and no Wii and I doubt that many would...

The serial modes for the GBA core are not implemented as far as I know and there are multiple modes (5 I think?). This would be a pretty massive undertaking due to its complexity so I shouldn't expect it any time soon, if at all. You can try the GBA2P core for local single-MiSTer multiplayer, it's pretty awesome. So I've been told on Reddit. That ...

Since there's a GameBoy SNAC Adapter, can I link MiSTer with a GameCube/Wii?

Besides misterfpga.co.uk, where can I get SNAC controller adapters with a USB connector?

The core must be rebuilt to use the pins for analog out. Basically just this line has to be removed: https://github.com/RobertPeip/PlayStation_MiSTer/blob/main/PlayStation.qsf#L54 Keep in mind that analog out isn't fully polished yet anyway, so if you really need it, it's best to wait some more weeks. Oh I see. The dual RAM option has been kept ev...

If the second sdram module support is enabled, analog output from the I/O board gets automatically disabled (they share the same pins after all).

But I don't use a 2nd sdram module.

Figured as much, thank you.

I get a black screen with my CRT using component cables

Well the problem seems to be the fact that I'm using a CRT. I tried it on my HDTV and it works... sort of. Most games lock-up after the title screen even with fast boot on and some games will freeze temporarily or permanently during game play.

Flandango wrote: ↑Sat Nov 27, 2021 3:32 am Try renaming SCPH1001.BIN to boot.rom

Just tried it (also updated the picture), but it didn't change anything.

Hey there, I updated the main MiSTer core and added the new PS1 core to my Micro SD card via FTP and I already had the BIOS file prepared. Thing is, I get a black screen when loading the PS1 core, can't load the menu and I need to power cycle. I've included some picks, can anyone tell me what I'm doing wrong?

Oh, PS1 gets it's forum before the Saturn, interesting....

To test the PS1 core: - Have the RAM you regularly use in the first slot as usual - Add extra RAM to the second slot, with the side marked "facing outwards" facing outwards - Flip SW3 To run other cores: - Remove the secondary RAM you added for testing - Put SW3 back to its original position Still doesn't work. Read on a Twatter post tha...

Lightwave wrote: ↑Sun Nov 21, 2021 9:11 pm You need to flip the SW3 switch on the board.

I just tried every switch with just a single RAM stick in the left slot, but nothing worked.

How do you test that it works/don't works? Did you insert the right direction? (as the PCB states: this side faces outwards) All other cores don't make use of it. e.g. you can't use the gameboy core with sdram only in the "analog board slot" Overall, please don't start a hype for a second sdram. If I wouldn't have made the whole developm...

Strange, I am unable to use both slots for RAM on my DE10-Nano. The slot that's used for the IO board doesn't work with RAM. I've tried my 32MB and 128MB in the other slot and they both work, but neither work on the slot where the IO board was setted. Anyone knows why?

Mr. Encyclopedia wrote: ↑Wed Nov 10, 2021 7:51 pm I asked srg on Patreon about the potential for a beta core release and he said it's not ready yet, and indicated his goal was to get it from dual SDRAM to single SDRAM before any public releases. Makes sense to me.

Let us pray to the FPGA gods that he can make it happen!
