Imagine if it's actually the same for cv1k games, finding the 'switch spot' for even a single game could take an eternity.
I'm working on exactly that. But i can say 100% that on pcb, at least
some parts, are fine-tuned
per-scene, outside the general CPU %.
That means that, for a few spots to trigger the appropriate slowdown, the CPU would beed to be in the low 20s, which will break the rest of the game. The good news is that, those spots are few and not really significant in terms of scoring or difficulty, if the overall CPU is set just right.
For example, i find Mushihime-sama (ultra) to run very well at 38% CPU. No blitter value, just underclocking. All the important slowdown is triggered, with a few small exceptions. Sometimes there is a bit more slowdown than it should, while some scenes have a little less, but it is well within a 90% fidelity in my opinion, which is pretty damn close.
38% seems to be the sweet spot for Futari 1.0 and 1.5. as well (there is a small stutter in menu and after defeating a boss when the screen fades to white, but really minor).
Espgaluda 2 (Muchi Muchi Pork as well) on the other hand, seems to be programmed a bit differently. As far as i can tell, it uses quite a bit of the CPU to load some assets in realtime. It hapends at the begining of level 1, randomly in level 2 and middle of stage 3. This translates into small stutterings for about 3 - 4 seconds. The lower the CPU is set, the more noticeable the stuttering is. So, for the slowdown to trigger when entering the kakusei and ultra kakusei, but also mitigate as much as possible the stuttering, a CPU of 46% is atm my choice. It does not trigger some minor slowdown (just like with the other games), but it does when the screen gets saturated with purple, very very close to what you get on pcb. High level scoring is possible (i managed 32 mil on stage 1 on my phone
), though if it weren't for the CPU decompressing the assets in realtime, a slightly lower CPU value would have been even better.
Ibara BL is smooth and gorgeous, very very close to youtube pcb videos at 48 % CPU. Trains in stage 3
maybe have a bit more slowdown, but it's pretty damn close.
