Why do almost no RPGs from PortMaster work properly on RG353VS?

Hi everyone,

I’ve been trying to play various RPGs/roguelikes from PortMaster on my RG353VS with ArkOS 2.0 (02092025), but almost none of them seem to work correctly. I’m running into different issues depending on the game, including crashes, broken saves, wrong resolution, or unreadable fonts.

Here’s what I tested so far:

Undertale - breaks save after a few launches

Angband - wrong resolution

Arkovs - font is too small

Brogue - font is too small

8 Bit Buccaneer - not working

Shattered Pixel Dungeon - not working

Terminus - not working

Labyrinth of Legendary Loot - not working

Cataclysm: Dark Days Ahead - exits after starting a game

DoomRL - freezes after start

Dungeon Crawl Stone Soup - not working

Infra Arcana - bigger fonts are broken

It feels like basically no RPG port from PortMaster is fully playable on RG353VS.
