Re: Grant’s multi computer - Need Help

Are your clocks configured correctly? SBCTextDisplayRGB looks like it's set up for 50MHz, but I think your clocks are set to 112 MHz. Even with 50 I think your pixel clock is 25 MHz, so you need to fix CE_PIXEL. Yes, you are right I changed the main clock. is no video but the screen is not going to...

the normal headers work, but you have to solder them in place as the pins do not completely goes through the holes.

If the Neo geo core is ever created be able to fit the MiSTer in a NEOGEO X Dock will be great (might not be the best for the fan exhaust): https://www.aliexpress.com/item/NEOGEO-X-Dock-for-NEOGEOX-handheld-console/32839080654.html https://www.aliexpress.com/item/Raspberry-PI-3-Cables-set-for-NEOGEO...

Re: SDRAM board

you can order 40pin L header and cut it by 3pins. PRPC040SBBN-M71RC is little bit longer than a regular 40pin L header. A PRPC040SBBN-M71RC is 6mm * 6mm https://www.digikey.com/products/en?keywords=S1121EC-40-ND Contact Length - Mating 0.230" (5.84mm) Contact Length - Post 0.220" (5.58mm)...

Re: USB Hub board

It's better to solder LED15 (power). It's not simple power LED - it's ON only when USB hub is initialized. So, it's kind "OK, it works now." Yes I was planning on it. But I have to test the LED with the resistor I could get the 510 so I bought 620 and 430. I think you went for red for the...

As Newsdee said the issue is with the RAM bandwidth to access the roms data.
