They should store it on Internet Archive, other archival service or Bitcoin sidechain. But at least it's less spammy compared with most data inserted to Bitcoin blockchain through Ordinal.
One huge concern I have is using recursive inscriptions to hold code that can be assembled into an executable - in this case the SNES emulator... What is to stop using the chain to distribute malware or C&C code for it?
Nothing can stop people from doing that. But as long as software you use (e.g. wallet) doesn't execute binary or code by itself, in practice there's no security risk.
