• ScummVM core: v2.6.1.3-11-gf821940
• RetroArch: 1.14.0

ScummVM game/engine

Additional context

• If you load the core only from retroarch (without loading any game) and start it, can you reach ScummVM GUI? Can you add the game from inside ScummVM GUI? If yes are you able to launch the game from the internal GUI?

• Can you provide retroarch logs?

• Can you test also with this freeware game from scummvm site?

[sonic65101]

1. Yes. The ScummVM core launches to the GUI. Neither Hi-Res Adventure 1: Mystery House nor Starship Titanic were detected, however, Beneath a Steel Sky was detected, and could be launched without crashing both from ScummVM's GUI and RetroArch's Load Content option.
2. Log from trying to launch Hi-Res Adventure 1: Mystery House. retroarch.log

The two engines from your test are not available in the 3DS build, as they are flagged as highres, which is not supported on this platform. This flag is coming from legacy libretro core. This is the list of engines currently available in 3DS build:

access
agi
agos
ags
bbvs
cge
cge2
chewy
cine
cruise
versailles
director
draci
dragons
drascula
dreamweb
glk
gob
griffon
groovie2
hugo
hypno
illusions
kyra
lol
eob
lab
lure
made
mads
riven
myst
mystme
parallaction
queen
saga
sci
scumm
scumm_7_8
sherlock
sky
supernova
teenagent
tinsel
tsage
tucker
voyeur
foxtail
herocraft
xeen

However there are two points:

• The core should not crash that way if game is not recognized. This will be investigated.
• The _highres=no flag is not specified for 3DS in standalone ScummVM. I've have enabled it in this build, can you test it?

I get a 404 page when trying to download the linked build.

With that build, both Hi-Res Adventure libretro/scummvm-upstream#1: Mystery House and Starship Titanic are detected by ScummVM's Add Game option, but only Hi-Res Adventure libretro/scummvm-upstream#1: Mystery House launches. Trying to launch Starship Titanic displays the message "Could not find titanic.dat data file." and then closes ScummVM/RetroArch, returning to the 3DS Home menu.

[spleen1981]

The dat file is included in scummvm.zip, available from retroarch content downloader. You can download for testing from here: https://github.com/scummvm/scummvm/blob/4bf45d922baaf68552c9936491d34361ffb467f2/dists/engine-data/titanic.dat And add to scummvm / extra folder in system

Starship Titanic also launches once the titanic.dat file is present.

do those highres games look like are running properly? any graphical issue?

[sonic65101]

Hi-Res Adventure libretro/scummvm-upstream#1: Mystery House runs fine. Starship Titanic starts out, just with audio stutter, but it slows down visually and audibly to the point of being unplayable once the ship crashes into the player character's house, though I think this is due to the 3DS's hardware.

I understand there are no real issues directly related to highres flag on 3DS, so I guess we can enable it. Also crash on unrecognized game is fixed by 6ec43063d4d9057c522edc459c3bee17ece51514
