I mean, when you see it's a few distinct graphics instead of there being obvious hints of some processing going on it becomes clear it's being assembled out of a few pre-existing graphics. I guess I jumped on it because I saw at least somebody attempt to use polygons thinking that Phantasy Star did ...

They aren't rendered on the fly, they're prerendered images (more like predrawn) that get assembled together to make the dungeon. This is a very common thing among all dungeon crawlers. The exception to the rule that comes to my mind is Shin Megami Tensei on Mega CD, that one seems to be using Wolf3...

I forgot on which of the threads we had discussed this but whatever. I recall that we discussed that a handful of sectors from the lead-in are actually readable because they end up in the buffers — not enough to build an entire TOC, but a quirk nonetheless. Is it possible to try to peek at the buffe...

Nah it's not just you, it's barely dropping any health items. One issue I notice is that regularly the sound goes bonkers and ends up playing really loud noise (the music itself seems to continue just fine, looks like the PCM sound effects get broken). Usually it fixes itself after a few more sound ...

You missed the initial write in InitInput. Either way, I rewrote the whole thing as a state machine that changes what to do every frame and includes the reset sequence for both mouse and keyboard (・＿・) (especially since the latter may actually need it if you press Reset in the middle of reading it, ...

Except my init code actually sets it to 0x40 then goes to initialize the video hardware (which does take several frames) before it ever gets to even attempt to go into the detection routine and it still fails to see the correct ID (and the code doesn't bother retrieving a peripheral ID again if it d...

For the sake of keeping track of this: when retrieving the peripheral ID you must absolutely make sure to read the TH=1 bits first and the TH=0 bits later. I still want to see Body Count's code though, it's possible it's indeed doing it backwards and it somehow works with an actual mouse (but could ...

Some more research related to mouse packets: Body Count is unable to detect the mouse in Fusion and I noticed that the mouse broke in Arkagis Revolution recently too, and the latter definitely doesn't care if the mouse is instantaneous or not. The only big change I did recently was changing the inpu...

It's possible it's not the MCU that's too susceptible to noisy power (though that probably isn't helping it) but the optical part. If the lights fluctuate too much I could see it causing the photosensors pick up spurious motion (and hence causing the random values). Now I also wonder if there's enou...

…that leaves me wondering what happens when you first set the latch register (does it halt where it was at that point, or does it expose what would have been the last "latched" value, i.e. acting as two separate registers over the same address?). Then again, it didn't occur to Sega to latch the HV c...

I imagine Control mode is basically "emulate a D-pad"? Especially since the Master System controller calls it Control Pad (the term Direction Pad came with the Mega Drive). (EDIT: yeah, it toggles whether it acts like a normal controller or a trackball) I have to admit i don't know too much about th...

Added Lemmings 2 to the list (spoiler: same deal as every other game that isn't Jimmy White).

As dumb as this may sound but… what's the setting for the HV counter? Is it running or latched? Because I wouldn't be surprised if the lightgun code wants the HV counter latched, while unrelated code may expect it to be running.

Well yeah, a mouse that does clamping will have to act like overflow never happens, I mentioned it just to help account for that one edge case (blurgh). Besides, the usual way to handle overflow is to drop the packet, while clamping at least doesn't completely drop the motion (and you could even spr...

So I was thinking about the possibility that somebody may end up making either an adapter for USB mouses to Mega Mouse, or outright replacements for the Mega Mouse (since while it's still cheap, ball mouses honestly are awful with their tendency to catch dirt). In the case of the latter, the obvious...
