A soccer map where players can only shoot the ball, rather than shoot and drive into it. TBD if its genius or just super annoying...#nesdev #gamdev

It has been 0 days since I finally got 2 VRC6 IRQs firing in one frame on the NES. Using them to swap in the flag animations for Rally Rally Rally title screen. #nesdev #gamedev

Room transitions working in Janus. Kept it simple and dropped about 80% of the IRQ nonsense I was attempting before...#nesdev #gamedev

"Joust" races have been a tricky mechanic in Rally Rally Rally. Still trying to find the right mix to make it interesting for 1-player... #nesdev #gamedev

Trap deployments working. Guess I have to implement an enemy real quick so they can do something! #nesdev #gamedev

OK, just implemented simple input buffering for movement and actions and glad I did. Rolling into a buffered shot is so cool! #nesdev #gamedev

Dullahan Software @dullahansoft.bsky.social · 10/07/2025
Yeah, with this I am using a jump table. So on the left is a CA65 enum with all the states (including transition states). The middle shows the jump code and part of the table, and then the last are all the subroutines that execute for each state.

Basic state machine with movement and projectiles now working. Up next, rolls & traps! #nesdev #gamedev

But how much boost is too much boost? #nesdev #gamedev

Inspecting drivetrain power levels. Something is up with my primitive rubber-banding and why isn't the power dipping on collisions?! #nesdev #gamedev

So maybe you have a point about the boost having too much juice.... #nesdev #gamedev

Increased drag and a lil' Y bounce and cobblestone driving feels good--I mean bad....I mean you know what I mean #nesdev #gamedev

Dullahan Software @dullahansoft.bsky.social · 05/05/2025
I wonder if I can make driving on cobblestone here just as bad as it is in real life #nesdev #gamedev

Hitting the limits of 12-n vector maps for CPU piloting (map is on the left). Even with reduced speed and increased cornering it's a tough time on a course like this! #nesdev #gamedev

Testing the new City tile-set. These straight race courses are an experiment. Will be interesting to see how ppl like them in playtesting (hoping for chaos with collisions and missiles) #nes #famicon
