Holy shit is this old.
But gold.
If this is the one i remember, since even the mega link of our saviour a few posts back has fell, and i'm not sure but i think RyonaRPG, which is the only one with recent posts, is a different game.
Am i mistaken?
EDIT: Apparently and from what i can understand there is RyonaRPG and RyonaSaga which now has the character from ERyonaAction (The girl with the axe and armor/helmet?). There is a page for "core" versions, and that other thing is an updates uploads dumpster. Can't get any core version to work yet, as either i get an error pointing to line 20 (27 on some updates) of a random file, or it just crashes and closes.
But goddamn i'm going to keep trying as apparently they've implemented some of Hinayua_R18 Sana's sprites from Fortune Summoners, and boy that'd be great to see
EDIT 2: You just need to download and extract both of the following files in the same folder:
core0127
core0121
(I have no idea what purpose serves the file below the last one, the " その2 " one)
Link: dev.rsaga.org/core/
The character from ERyonaAction is named Aria.
EDIT 3: whelp...this is...not a sidescroller
