Announcing v0.2.0 of my homebrew SNES audio driver.
This release stabilises the 2 breaking changes I made to the audio driver months ago (in the beta releases). It also fixes a lot of small bugs and items I had on my ever growing todo list.

I have released a 2nd beta of my SNES audio driver.
It adds transpose analysis to the compiler to detect all out-of-range notes caused by driver transpose.
I've also rewritten the timer code to increase the max bytecode sleep duration to 65535 ticks.

This beta moves `_` and `__` transpose MML commands out of the MML compiler and into the audio driver, so the semitone offset will affect loops and subroutines.

Extending my Furnace to Terrific Audio Driver project so that it can also accept Impulse Tracker files wasn't too difficult, though there's still work to do and everything needs to be tested. Internally it converts the file to Furnace-style representation and then converts again to MML.

Here's my #SNES mouse-controlled shooter game so far! It's definitely far from being 100% done, but it's in a state where I feel comfortable showing it off and having people try it out! Multiplayer and regular controllers are supported.

Here's an upcoming #SNES beat'em up that might be worth keeping on you radar:
"Triple Impact"
By DigiFox
It's still somewhat early in development but so far it's already looking really atmospheric with some solid sprite work.

Yesterday I finished a playtest build of my SNES game
I'm one step closer to releasing a game.
Lots of stuff I've got to do in 2 weeks: Enemy projectiles, enemy graphics, boss, title screen, game over screen, pause screen, credits, and more levels.

SNESdev daily log 1:
Finished drawing the tileset.
I ran out of time (if I'm to meet my self-imposed deadlines) but this is a good place to stop.
I wasn't able to come up with a left/right wall design, it's just a 2px black border.
(Pink is transparent and dark-magenta are unused tiles).

Sorry for the lack of updates. I've been without Internet for the last week and do not know when it will be fixed.
On the plus side - I have been documenting and re-analysing my automatic joypad tests (1 or 2 a day) instead of watching YouTube.

I really wanted my small SNES game to have smarter pathfinding than just moving randomly or just using atan2. I looked at some 90s game dev magazines for advice but it looks like Dijkstra maps work great and let me reuse work across many enemies if I want.
