gb-ctr VS pandocs

Gekkio's GB-CTR is a good reference of the SM83 (Gameboy CPU) with access pattern withM cycle accuracy. The GB-research repo by the same author also contains a lot of information.

In case you're interested in the precise pinout, see Appendix D in gb-ctr: https://github.com/Gekkio/gb-ctr

Does anyone know of good documentation beyond: - Pan Docs - The Cycle-Accurate Game Boy Docs - Complete Technical Reference - Nitty Gritty Gameboy Cycle Timing

The thing about the Game Boy (or most consoles, really, but especially the Game Boy since it uses a custom CPU) is that we don't know all the details. People have had to reverse engineer it to figure stuff out. /u/gekkio is one of the people doing that work, and his technical reference and test suite are the (ongoing) results of that.

This is a great resource: the complete technical reference.

Use https://gbdev.io/pandocs/ , https://gbdev.io/gb-opcodes/optables/ and https://github.com/gbdev/awesome-gbdev to get started.

Probably the most important one (the one I've used the most for reference) was the Game Boy Pandocs.

Based on my reading of https://gbdev.io/pandocs/

The pandocs are probably the most up to date documentation about the GameBoy in existence. It's a console which is still under active research - these days it's very focused on the extremely low level hardware behaviour.

The Pandocs are easy to read and contain pretty much everything you need to know to get a basic GB emulator up-and-running. The section on the Power-Up Sequence would answer this question for you and then some. You would've gotten the answer to your question yesterday if you looked at the Memory Map section, which tells you where ROM is mapped, and then some.

For actual documentation, you probably know the pandocs, but there are a lot of more specific information in the docs linked in their references, especially the cycle-accurate GB docs, the GB complete technical reference by Gekkio. You can also check the source code of the relevant test roms, like the Blargg’s test roms for more general behaviour and the MooneyeGB test suite for more specific things.

For the Game Boy, being a closed system, there's fewer resources. Nintendo made a programming manual, but it's not very good. Pandocs is a good supplement: https://gbdev.io/pandocs/

Very cool article!

If you want to know more about the hardware side of the Game Boy (Color), have a look at the Pan Docs: https://gbdev.io/pandocs/

It's been revamped in the recent years, in terms of presentation. I do kind of miss the old version which had a refreshing "old-school" UI like the RFCs of the IETF, but the newest version is IMHO much more usable when developing an emulator.
