Activity for Wheefun Computer Prototyping Kit
-
Phillip Kilgore committed [r16]
Began work on 6502 implementation.
-
Began working on NES PPU implementation.
-
Added attributes to Mode 0.
-
Began implementing text mode 0.
-
Began working on Text Mode, added an implementation of the CGA 8x8 font.
-
Fixed mirroring code in Mode A and updated figure in specification.
-
Updated documentation and got rid of EXT bit. Former Mode0X is now in Tandy/PCJr region. Added unit tests to core for Memory. Fixed issue with nametable writes where attribute data is corrupted. Refactored Pattern Mode to afford pattern modes at other bit depths.
-
Began working for documentation on the VAI core (to be used with the same module in Java)
-
Fixed a lot of the bugs in the port of Jadzia, except that in the demo some multis peg the attribute byte to $FF for some reason.
-
Began porting Mode 0X demo, which has not survived and has revealed some bugs with the way memory is handled.
-
Very basic untested Jadzia implementation derived from a private implementation. Added primitives to help with color, added VideoCore interface. Added stub where examples will go.
-
Broke off into modules; added core and VAI module.
-
Preparing to modularize the Java implementation
-
Began working on Bus implementation (still very much a work in progess).
-
Began working on Java implementation. Added Memory and two implementations thereof.
-
Initial import; added license and basic directory structure.
