One thing I do when porting or composing music is to hide the PSG channels since I'd rather the FM take precedence, here's what this song sounds like when split between FM, PSG and the DAC & Noise tracks:

In my works, PSG is most useful for normalizing channel panning, since the YM2612 can only do full panning, no partials! It can also work as a good echo.

Sound Effects are also a big factoid so to avoid sudden stops in music channels, redundancy is necessary. In other words : despite the fact we have 5/6 FM and 2/3 PSG channels, in reality we only have about 3-4 channel polyphony.

I'm going insane

Since my site is down guess I'll release it through here instead:

Play Sonic 1 with an analog controller!

Fun fact : in Blue Spheres it takes 45 seconds for the speed change as opposed to 30 seconds in normal S3 / S3K.

Surprisingly got some folk from other social media telling me they didn't know there was a demo...

I thought I was being too annoying @.@

Well just in case, here's a link for those who missed it

Gatoslip now has S&K lock-on features

For awhile I knew that S&K checked for the attached cartridge's header to execute it's code, but little did I know just how far one could go beyond just allowing a full version of Blue Spheres...

For this in particular, I put a dummy Sonic 2 header around the 3MB mark (game is too large and won't mirror) and exploit the fact it uses Sonic 2's Sound Driver loading routine by having code that hijacks the gamemode address table and runs its own code on top.

And I can go further than just a simple mock scene before Blue Spheres :

When you fit S2 into S&K, you get KtEiS2

When you fit Gatoslip into S&K, you get P&K

This one sleep deprived idiot came to me on DMs with this screenshot

Having done this stuff for years I knew right away those colours are in BGR, hex values in increments of 2

Once translated, it came up like this, the second one I used the "gold" and "red" colours at the bottom.

First thing I noticed is that the order is backwards compared to the games, so I flipped the image vertically and made a comparison gif

(don't mind the brightness change, different programs preview colours differently)

Observations:

...dude says he's sick of looking at Pokémon stuff yet doesn't respect it when I say I'm sick of Sonic stuff.

This small part did catch my attention however, seems there was some plan to use Shadow and Highlight mode at some point.

For those unaware, Shadow and Highlight mode allows for stuff like this:

QUICK EDIT : comparison between beta and final palette:

Found the placeholder title screen

(final version for comparison)

In the original game, there is 1 frame of movement lag every time you jump. This isn't because jumping is a heavy task, but because it skips over the rest of the player's code on a successful jump via a "addq.l #4,sp" (add to stack pointer, essencially forgetting the return point). I decided to change the line to a "move.l #SpeedToPos,(sp)" so that it applies momentum the same frame, removing the stutter.

(More accurately, it should've been #ObjectFall to apply gravity, but I'm keeping it this way. Enjoy the extra jump height~)

This just happened and I don't know how to feel about it.

This is M68k programming in the perspective of an Artist with little attention span.

Wanting to change the object system as it will make things easier in the longrun, more Object RAM and flexibility is what I'm looking for with this.

Some of that stuff you guys followed me for...
