MBC30 Compatibility Reference Table

MBC30 is a variant of the common MBC3 mapper that can access twice the memory as the regular variant. MBC30 allows for up to 4mb ROM and 64kb SRAM over MBC3's 2mb ROM and 32kb SRAM. It is only known to be used in the Japanese version of Pokemon Crystal, mainly for Mobile System GB features.

The added space provided by this variant is considered beneficial especially for ROM hacks. For example, Pokemon Coral (2022 demo and up) uses it for sampled cries and other extra content.

Note on hardware compatibility

Everdrives will not work, unless an OS update is released. Until then, you'll need to make/buy an MBC30 flashcart (such as this project, or BennVenn's custom cart), and have reflashing tools.

Converting PCF fonts to TTF

Let's assume we're converting helvBO24.pcf, a version of Helvetica Bold Oblique for 24px that comes with X11. The output file will be helvBO24_fixed.ttf.

Step 1

Convert the thing to bdf through pcf2bdf

pcf2bdf helvBO24.pcf > helvBO24.bdf

ASMDOC

(a.k.a Hell on Earth, I'm Sure)

Essentially, this is just a Javadoc-esque thing loosely applied to assembly language (primarily geared towards RGBDS ASM)

The opening and closing tags are just a line containing only ;;--, everything inside the ASMDOC must begin wih ;; .

Mapping

Easily opened with the latest version of [Polished Map][1] (4.5.4 as of writing).

object_event data is a little misleading -- movement constant has wrong context (e.g. SLOW_STEP_LEFT is inaccurate)
