Re: IOBoard VGA to 15khz PAL CRT via RGB Scart

Shifting on some cores are possible due to lack of precise info when hsync/vsync start on specific system. This is completely different issue not related to squashing shown in the first post. To make exact vertical/horizontal position as on real HW, need to have real HW and CRT monitor which in most...

Re: USB Hub board

It's unclear did you solder VBUS control circuit or not. If not, then it should be properly bypassed by 0 ohm resistor/jumper. Check if 5V is present on downstream USB connectors.

Re: Tip for anybody having low lag syncing problems on the LCD TV

In most cases TV (and even many monitors) have fixed 60Hz refresh rate and it's never changing. So stuttering will be always present on such TV. And stuttering even more visible when input refresh is close to 60Hz. For example 50Hz stuttering on fixed 60Hz TV is less noticeable.

On HDMI it's correct.
On VGA some games are 90deg some 270deg. This is normal.

Re: Tip for anybody having low lag syncing problems on the LCD TV

With vsync_adjust=1 it should not stutter. If vsync_adjust=1 stutters then it means your TV doesn't sync with input refresh. It's unusual for most TV to do a sync as it's mostly monitor feature.

Re: IOBoard VGA to 15khz PAL CRT via RGB Scart

Nothing wrong with the cable.
CRT TV depends on vertical and horizontal frequencies. It's usual to have different position and different size if video parameters are changed. And of course each core generates its own frequencies according to original system.

Or do they all require separate ground? (which seems to be the case in the VGA 15-pin connector)

They are digital, not analog.

MiSTer is about starting the core and use the emulated system. Menu system is something you don't have to notice at all. Its task is to help to load/mount the file and change couple settings, otherwise it should do all work in background, invisibly. Don't make cult from menu! Don't torture yourself ...

i don't know about 1440p - probably it's 2K, not 4K.
Scaling to higher resolution has less artefacts, so MiSTer scales to 1080p much better than to 720p.

Re: PICO-8 on MiSTer Linux

There is gameduino (first one, not the current one) FPGA project with exactly tiles and sprites. Just need to be ported to MiSTer with addition of some CPU. I suggest to use ZPU as CPU - it has gcc toolchain.

Re: Calling all developers - „Sync to core“ is great

Sync option in GBA has nothing to do with refresh rate. It's because GBA timings don't fit into integral number of lines (because GBA uses LCD, not TV). So at the last line GBA core freezes for short time to let the current line to be drawn fully. Without this TV gets incomplete line with misaligned...

For analog video input it's important to detect the pixel clock properly which is not trivial job. This is main problem of generic stand-alone scaler implementation.
