No Game Will Start Just Grey Background

[Hecky666]

Hi there,

im new to the misterproject.
Got a single de10nano running and updated it with the mr fusion update_all-script.
Dont have the ramupdate / usb hub / io-board jet. Ordered them, but sill waiting for arrival - availability in germany is horrible

Genesis / TG16 / Atari and some (old) arcadecores are running nicely.

But I am not able to start any nintendo rom f.e. nes.
The screen stays allways grey.
I can see the "loading-rom-bar" (on snes-games) but nothing showes up.
I can still access the menu via F12 - so it does not hang up just wont boot the rom properbly.

Tried different roms from different sources, non of them worked.
Also tried to duplicate the boot0.rom and renaming them to ..1.rom/..2.rom/..3.rom ... nothing changed.

I am not sure about the headers mentioned in this forum.
I tried to use iNES information but dunno how to read it
I attached a file from a .nes game.

Please can someone help me?

You need a memory module for the NES core, it is not optional.

See here for a list of the cores which require a memory module to function:

Thanks a lot.
Was on that site but misinterpreted the info.

Do you have any suggestions on how to improve the wiki page, so the information more easily interpreted?

I have seen the two pages for SDRAM requirements for consoles and computer cores on the docs site, however not everyone finds that as an information source first, I am still interested in how the wiki page was misinterpreted from a new MiSTer users point of view so an effort can be made to improve it.

My interpretation of the wiki site is if it has a specific SDRAM speed requirement listed for a core, then SDRAM memory it is needed for said core, unless is states SDRAM as being optional, however others may not interpret the page in this way.

I think I’d find it easier to understand if the optional and required cores were separated - maybe at the start of the page list the ones where it’s optional and have text saying the cores can use it but will run without it, and then list the ones where it’s required and specifically say “the following cores will not work without SDRAM” or something to that effect.
