It builds the following rom:

pokepinball's Issues

Scrolling instead of screen switching?

Something I always wondered about. Would it be feasable to remove the screen switching when the ball goes to the upper (or back to the lower) area and just have it scroll to there? Like in GBA poke pinball?

(This is not a feature request, I just want to have some more technical info)

Define constants for OAM entries

LoadOAMData and LoadOAMData2 take an oam entry id as input. Currently, these ids are hardcoded everywhere. Instead, these should be constants.

Bad:

ld a, $cc
call LoadOAMData

Good:

ld a, OAM_BELLSPROUT_BODY
call LoadOAMData

or perhaps:

ld a, SPRITE_BELLSPROUT_BODY
call LoadOAMData

Dump remaining Stage graphics

The first two stages' graphics in StageGfxPointers_GameBoy and StageGfxPointers_GameBoyColor have been dumped. All of the remaining stages' graphics need to be dumped in the same way.

Add `.gitattributes`

Adding a .gitattributes file similiar to the other pret gbc repo's will help enforce normalization's of line endings. When I get some free time i'll create a PR for this.

Continuous Integration & Symbols Branch & SHA1

It might be worth setting up continuous integration and Symbols branch for this repo similar to pokecrystal. Also we should standardize on SHA1 hashing across all the repos.

• Continuous Integration
• Symbols Branch
• MD5 -> SHA1 #38

Issue is related to: pret/poketcg#117

EVOLINE_ is misnamed

The "evolution line constants" are misnamed. They only represent mons that can be caught on the field.

Create Macro for LoadVideoData entries.

An entry's format is:

dw "Address of data to load"
db "Bank of data to load"
dw "Destination address for data (in VRAM)"
dw (Num bytes to load << 2) | something gbc palette related | something else

Bits 0 and 1 of the last word are flags for whether or not the data is GBC-palette-related, however I haven't researched the exact details of those two bits, yet.

Won't compile with RGBDS v0.5.2 as suggested, but compiles fine using RGBDS v0.6.0

Thought it would be worth mentioning for anyone wanting to compile under Cygwin64 for 64-bit Windows using 64-bit RGBDS.

Same thing goes for the Pokepinball-generations decompilation project.

Figure out what Data_13685

Data_13685 contains data about evolution lines, but it's unclear what the data represents. It needs labeling, and maybe a macro?

Refresh build instructions

• The install instructions mention installing dependencies using apt-get only
• The RGBDS install instructions are outdated
• The Git clone link (in INSTALL.md) still refers to huderlem/pokepinball

Update INSTALL.md with submodule instructions

The reverse engineering submodule was added after the Installation instructions. It should be updated to reflect that.
