Wait, PI for
FUUIN.EXE is mainly blocked by the high score
menu? That one should really be properly decompiled in a separate
RE push, since it's also present in largely identical form in
REIIDEN.EXE… but I currently lack the explicit funding to do
And as it turns out I shouldn't really capture any of the existing generic
RE contributions for it either. Back in 2018 when I ran the crowdfunding
on the Touhou Patch Center Discord server, I said that generic RE
contributions would never go towards TH01. No one was interested in that
game back then, and as it's significantly different from all the other
games, it made sense to only cover it if explicitly requested.
As Touhou Patch Center still remains one of the biggest supporters and advertisers for ReC98, someone recently believed that this rule was still in effect, despite not being mentioned anywhere on this website.
Fast forward to today, and TH01 has become the single most supported game lately, with plenty of incomplete pushes still open to be completed. Reverse-engineering it has proven to be quite efficient, yielding lots of completion percentage points per push. This, I suppose, is exactly what backers that don't give any specific priorities are mainly interested in. Therefore, I will allocate future partial contributions to TH01, whenever it makes sense.
So, instead of rushing TH01 PI, let's wait for Ember2528's April subscription, and get the 25% total RE milestone with some TH05 PI progress instead. This one primarily focused on the gather circles (spirals…?), the third-last missing entity type in TH05. These are rendered using the same 8×8 pellet sprite introduced in TH02… except that the actual pellets received a darkened bottom part in TH04 . Which, in turn, is actually rendered quite efficiently – the games first render the top white part of all pellets, followed by the bottom gray part of all pellets. The PC-98 GRCG is used throughout the process, doing its typical job of accelerating monochrome blitting, and by arranging the rendering like this, only two GRCG color changes are required to draw any number of pellets. I guess that makes it quite a worthwhile optimization? Don't ask me for specific performance numbers or even saved cycles, though
Next up, one more TH05 PI push!
