Thanks. Does it work with this Mister file?

I have my Mister hooked up to a JPAC in my arcade and have been able to use it for both Player 1 and Player 2 in Dual Xinput mode (Mode 3) successfully until now. At some point between end of May and now the 2 Player compatibility stopped working and now the Player 2 side only controls Player 1 (both sides are now Player 1). What is the VID / PID ...

Nice! Which TV is it?

Maybe your TV does not like to go much lower than 148.5Mhz pixel clock in 1080p so what you can try is to increase the pixel clock slightly. video_mode=1920,122,44,148,1080,4,5,36,150795 This video mode has an increased front porch from 88 to 122 with a pixel clock of 150.795Mhz @ 60Hz. This will go back down to 148.5Mhz @ 59.1Hz. Don't forget to d...

But I have to ask how did you get a hold of this? The newest version on the GitHub page is the one I was running before from 4 months ago (Arcade-Robotron_20200316.rbf) which had the Vsync length issues. Sorry I'm just learning all this as I go, so just trying to understand where some of these files come from since they are not on the official Git...

Try the attached core. The Vsync length has been corrected.

Does that mean only the Genesis controller works on all cores and for NES, SNES, PC Engine and NeoGeo controllers they only work on their own cores with SNAC enabled?

This is absolutely incorrect. Can you explain for example where are these 1.31ms lag if I have not use any circuitery on most of splitters. I got it from DB9 module https://github.com/Miguel-T80c/Genesis_MiSTer/blob/master/joydb9md.v . This module is clocked at 50Mhz and it divides the clock by 256 for the joystick state counter which results in 1...

Check out Antonio Villena's MiSTer devices. He builds them with a SNAC8 interface, implemented through a DB9 connector. Apparently SNAC8 has one additional pin compared to the offical SNAC7, but it's lagfree all the same. I'm running the ENCC/UserIO joystick fork of the MiSTer cores for that. DB9 connects to the same IO lines as SNAC but it is not...

DB9 is not the same as SNAC. DB9 still has latency because it has to poll the controller.

SNAC is directly connected to the core without additional polling.

Here is a patch for the kernel to fix the RetroUSB adapters: https://github.com/torvalds/linux/commi ... 31cdeb3d26

Apparently they need the HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE quirk. You can test this by adding usbhid.quirks=0xf000:0x00f1:0x100000 to /linux/u-boot.txt

Connect a usb cable to the UART port and connect with Putty to the com port as described here https://github.com/MiSTer-devel/Main_Mi ... connection.

If there are no inputs then the console will stay empty. Disconnect and connect a usb device to trigger the input devices listing.

You should get some logs of the input devices in the menu core and see if there is a difference between the Blisster and standard USB hub.

I checked the Genesis save code and it looks like it is not affected by this issue. The code is slightly different which prevents writing the save file during rom loading.

I found an issue with autosave where it will write a blank save during rom loading. This only happens if there is already a game with saves running and it writes to save ram just before the new rom starts loading.

I have sent a pull request for the SNES core but it probably also affects other cores like Genesis and Turbografx16.

A 1k-2k Ohm resistor on the sync line fixes the color issue with some Trinitrons.

Did this just drop? I was never able to get the SGB palettes and borders to work and now it does? The first version with SGB support was released in the beginning of May. Maybe you had it set to Gameboy Color mode? It only works in Gameboy mode. Would it be complicated to implement 2-player/multitap for the SGB games that support it? There's about...

Alone in the Dark for Gameboy Color is much improved, but there is some junk in between screen transitions. Pinball Fantasies actually lets you launch the ball now and play for awhile, but ends up crashing, but still an improvement over official current core. The junk with screen transitions is probably because a Gameboy normally does not show the...

Yes I suspected that IRQ jump too, but somehow most of the test roms passed on that one and I couldn't replicate it with consistency, I will continue to work on my testbench with sameboy as something to be compared to, maybe that can help find more bugs that are intermittent of take a long time to find. Here is a difference that I found compared t...

I have spent some time improving the PPU timings to make it more accurate to a real Gameboy. Pausing when fetching sprites for example. Also fixed issues with HDMA and STAT irqs and OAM dma. Almost all games are fixed in the issue tracker. Super Hunchback writes to SCX/SCY in an LYC interrupt just barely before mode 3 starts. The LYC interrupt trig...

Would it be possible for you to post the diff you made to the core's code or link to the original commit? I'm curious if this could also be applied to the other problematic cores and then be rolled back into main with PRs. Also curious why the high pass filter isn't universal? Here is the commit: https://github.com/paulb-nl/Gameboy_MiSTer/commit/3...

Are there specific NSF files that don't play anymore? I have just played some without issue. NES core 0526. MiSTer 0529.

Yes the aspect ratio is the same as you would see on a CRT. This does mean the 320 width resolution is a bit narrow because that's how it is on a CRT.

I added the high pass filter from the NES core which fixed the same issue for the NES core back then.

The audio waveform also appears to be centered better with the filter.

Can you try this core version to see if sound is working?

Thanks Artemio. Glad I could help to fix the patterns.
