Headed to @RetroGamingExpo this weekend? Are you a part of the #NES development community and/or want to learn more about how your favorite games are made? Join us Saturday in room F149 between 2 and 4pm to connect with fellow developers! #prge #prge2025 #nesdev #homebrew

this is how I've been spending my summer -- redoing this level's tileset in Pyronaut by psychotically overanimating it. The little orifices are possibly for player propulsion or suction and not supposed to be too numerous. #nes #nesdev

In #nes Pyronaut, working on a periodic room transformation in which the floors become harmful to the player.

In NES Pyronaut, hidden passageway using common practical effects.

In Pyronaut, some sand that sinks and slows down the player.

Movable holographic platform cubes in #nes game Pyronaut, each a projector of an otherwise invulnerable enemy. The cubes can be destroyed by one weapon and moved with another. Destroy the cube, destroy the enemy. This was @mteegfx design.

General moving platform blocks in Pyronaut. This is where you can kind of tell this is Simon's Quest though this required a surprising amount of edits to get it to work. #nes

floating eyeball block object in Pyronaut -- this serves as a platform and an enemy. Perhaps eventually vulnerable in some ways, like shoot it and its eye shuts. #nes

Working on some one off platform devices in Pyronaut. This one has an unintuitive puzzle element to it. #Nes

In the opposite direction, thus covering all 16 corner turning cases.

Pyronaut enemy Biri It slithers on the walls, floors and ceilings in any cardinal direction, turning when meeting a cornered wall or edge. Look at the little dude go -- yay. This is officially the last enemy added into the game. Some platforming objects are planned next. #nes

Test in the other direction, yeah X Y positions will definitely need some adjustments at each turn, adding and subtracting a specified value.

Crude test of a wall scaling enemy, the shell for the last basic enemy left to add into the game. This is actually surprisingly difficult to do. It's the 3rd time I've attempted something like this. I'll probably have to correct the X Y positions of the enemy at each turn. #nes

To edit the levels in Pyronaut, I customized an old editor of Simon's Quest (orig. called CursED, I asked for the source code very long ago) and made PyronEd programmed in VB6. A shell rom is edited with the level data, and a Java file transfers the changes to the current rom.

Pyronaut enemy Turon -- this bursts out of the pods from the background walls, then hops around and chases the player #nes #nintendo #romhack

#nes game Pyronaut to be displayed at #PRGE - Portland Retro Gaming Expo this weekend on old Nintendo Entertainment Systems -- come and see at booth 1014 -- yay
