Genesis GBA Turbografx works / GB NES SNES MEGACD doesn't

Hi there,
I followed the exact tutorial on this page :
https://github.com/MiSTer-devel/Main_Mi ... etup-Guide
But I can not load any GB NES SNES MEGACD roms/isos
That's strange because Genesis GBA and Turbografx roms and isos works well.
I downloaded and did the update_all script and tried after, same result
I have the basic setup for DE10 Nano right now: no RAM/IO/USB update.
I'm worried. Is my DE10 works correctly ? How can I check ? Do I have to return it?
Please advise. Thank you.

No RAM
The cores you list as having issues all require the SDRAM module to function, until you have one they will not work.
See here for details on which cores need an SDRAM module.

You need more ram, get the 128 and call it a day.

I was thinking about this possibility. I ordered the RAM and the other parts a few days ago, but I have to wait until next week to try it.
Thanks for your answer. I feel better now ^^

https://github.com/MiSTer-devel/Main_MiSTer/wiki - In the meanwhile, the wiki is a good thing to read up on so you can learn more about your new awesome game system.

This picture is taken from the MiSTer Wiki on github. It is one of the projects early 32MB memory module versions (v3.1 U).
If you are looking to buy memory for the DE10 Nano, I would recommend buying the new v2.9 128MB memory module.

However, the wiki needs a thorough cleanup & update. Badly.

On the setup guide (
https://github.com/MiSTer-devel/Main_Mi ... etup-Guide ) : " If you're using additional SDRAM" ... I didn't know I had to make the nes / snes games work. Since Genesis and PC Engine games worked, I didn't think about that at first.
Also, on this page (
https://github.com/MiSTer-devel/Main_Mi ... -use-SDRAM ) there is no comment about nes / snes working or not with or without RAM ...
So as lamarax said: the wiki needs a thorough cleanup & update ^^

In the first link, there is this under Manual Installation:
SDRAM Board (Optional, but is required for a majority of the cores, see wiki page for instructions.)
The first line above the table of your second link says:
The table of the cores requiring SDRAM Board to function:
I guess it could be made much more obvious, that's a fair point, but it says those cores require SDRAM. Then the couple that don't need it but it's an option say "optional" as well.
