Minecraft's Hidden PSX version is weird...

Can anyone tell me what that chest i found is? (Taken from the PSX archive channel:) “If you'd like to play the game yourself via emulation here's a link to a rom to download as finding a physical copy like myself is nearly impossible to do: https://www.curseforge.com/minecraft/... “ “Thanks to KazlsKoolx for ripping the game files to allow others to play the game” ------------------------------------------------------- TWITTER:   / vetatrn   INSTAGRAM:   / veteran.mc   DISCORD SERVER:   / discord   Music: Minecraft Volume Alpha - C418 Alphaver - ?
