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

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

Workshopping movement today. For now going with simple 4-directional with velocity a little under 1 px a frame. #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

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

Working on dino race courses, complete with palette-cycling lava... @kevynstott.bsky.social is the current speed good? #nesdev #gamedev

The meanest thing I've ever done...and in the 2nd level! Believe it or not that part was even harder in earlier versions. #nesdev #gamedev

It's been baby-steps with the 4-way screen transitions....Need to troubleshoot my IRQ next. #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

The new rendering code in Janus is working fine--why do you ask? #nesdev #gamedev
