Luis Montes @monteslu.com · 18/09/2026Part of it for me is I keep wanting to spend some time making detailed explainers of stuff, but the barrier to entry is so low to experiment on something new that my attention is quickly stolen. Maybe we need even more conferences now to force us into spending time communication/collaboration. 000

Reposted by Luis MontesJay McGavren @jaymcgavren.bsky.social · 19/07/2026The #ROMHacking community needs to get over their AI hatred, and quickly. Claude Opus and Fable are REALLY good at disassembling ROMs and commenting the code right now. Future models won't be, as they get optimized for corporate use. #ROMHack #RetroGaming #emulation #NES #SNES #homebrew 042
