Test Patterns & Blank Screens

[douganderson]

I've got the latest Mr-Fusion image running on a stock DE10-Nano. I've run update-all and pulled down the ROMs.

• A handful of arcade games seem to work fine, for example: Donkey Kong, Joust, Burger Time
• 1942 simply show a 'plaid' test screen (there are a number of games that just show a test screen)
• Track & Field shows a teal screen
• Golden Axe (and others) show Sending ROM #0 > Loading > Blank screen

Do I need more RAM? Is there some video configuration I'm missing? I'm running this through an HDMI audio extractor but it also fails when going direct into my monitor (an aging unit where I'm using an HDMI to DVI adapter)

Thoughts?

An SDRAM module is pretty much essential to use most cores.

I would also recommend thoroughly reading the wiki and watching a few YouTube primers before getting started. Video Game Esoterica has a good up-to-date video and plenty of content to help you out.

Here is an incomplete list of cores and their SDRAM requirements.
