Tip: Layer 3 backgrounds and tides disappear when you hit a message box, so unless you apply this fix, plan your level around that. For example, you can add a sublevel without layer 3 at the start/midpoint, and include your message there.

hi

Favorite videogames (in no particular order)

Romhacking stuff:



Some small tools that you may find useful:
  • Echo volume converter: converts the echo volumes from any SPC to values to use in SMW ports (since they need to be adjusted if the SPC doesn't use a master volume of $7F).
  • Frequency to pitch converter: converts a frequency value from Hz to the equivalent SPC pitch value. Mostly useful when making your own samples.
  • SPC700 ADSR/Gain converter: finds the ADSR/Gain command value from the values you see in SPC700 Player.
  • Volume and pitch calculator: finds the output volume given a global volume, channel volume, panning, quantization and $FA$03 values; also finds the output pitch given tuning, note and $EE values.
  • Linear gain calculator: finds an approximate linear gain value to obtain a certain change in envelope over time. I've used this extensively for my Plok, Spiderman and the X-Men: Arcade's Revenge and Winter Gold ports.
  • Max volume finder: finds the highest v command value in a given port. I use this sometimes to rebalance volumes in SPC2MML ports.
  • Panning fixer: small Python script that inverts all the pan values (yXX, $DB$XX, $DC$XX$YY) in a port. Useful for certain N-SPC games that use panning in the opposite way as SMW (i.e. they have y0 = left, y20 = right), for example Alcahest and Kirby Super Star. Also works for raw nintspc mml outputs.
  • SPC noise values: a list of all possible noise frequencies of the SPC, given the nXX value.

My Youtube channel: https://www.youtube.com/channel/UC9cNvJLq_-CbllV4qujzkNw. I mostly use it to upload my (not 1:1 SNES) ports, ASM stuff and levels.
