Re: Full Quiet - cryptic open-world mystery adventure platformer

I've played it for an hour, and my experience was quite bad. This game is poorly designed, nothing makes sense and nothing is explained. 4/10 - got stuck at the start for a few mins when couldn't reach ladder - couldn't enter cabin? Time running out to the 2am deadline - no info how to reload manual...

Re: Xeno Crisis is finally coming to SNES

It needs the coprocessor for the audio (there's lots of speech announcements), and it's not 1-to-1 given the resolution difference. Still it's a literal port to get Xeno Crisis on another platform, PS1 is coming soon.

Re: Xeno Crisis is finally coming to SNES

The comments say it uses a MSU-1 like coprocessor, which acts as an antipiracy measure too.

Re: Faster way to divide by 10

Truncating to byte before mod-10 would possibly cause wrong results. 0xff % 10 = 5 0x100 -> 0x00 % 10 = 0, should be 6 As for fast conversion, this topic has a lot written about it even in a modern context. I think Facebook's version was the fastest at least at one point, it combined ifs and a small...

That's going to be a PITA in asm no matter what design pattern you use.

Re: Full Quiet - cryptic run-and-gun exploration platformer

Congrats on finally getting it out, though it's 5 years late. Will there be a postmortem what caused the 5 year delay?

Re: disassembling/reassembling with cc65

Disassembling a complex mapper game like MMC3, where PRGs are in small banks and relocated to configurable places, is going to take effort. Start by playing the game and taking notes of what modes it uses, where does it place the banks. A CDL-logging emulator can tell you what is code and what is da...

Re: from C64 to NES, so a bit of a newcomer

It sounds good, but if you want to target actual games, you most likely can't use the expansion chips like vrc6, and will have some limitations depending on the sound driver.

Timing. Whoever happens to contact at the right time. The protocol can be seen in the official GB doc.

Re: Is it possible to make a game using Sunsoft FME-7 5B?

Yes, when targeting emulators you can pick any mapper. But if you want to produce hw carts, that choice may cause issues (both with NESes needing a bottom dongle and the potential repro availability of that mapper).

Re: GBC input timing

GBC does not have autoread like SNES. Games may read input at any time they wish, and as many times a frame they wish. It sounds like this is your issue, and when you supply input too late, the game applies it one frame later. I don't think there is any "latch" hw signal, but I'm not 100% ...

Re: Switching CHR-ROM to CHR-RAM

No, because there are multiple options that can work. Enough PRG, enough CHR (-RAM if needed), enough RAM.

I have to say Zolionline does quite good 16-bit art as well.
