To be honest the current joypad routines are a mess and the single joypad routines doesn't handle "triggers" correctly (especially the 6 buttons version).

Add routines for :

• Sprites
• Text output
• Scrolling
• Palettes

Add HuC wrappers!

Create a sample makefile with all the necessary options to choose between pceas and cla65

It seems feasible (check SF2').

Sprites routines + helpers + consts.

Write coding guidelines!

Todo:

• map_load : Load 8x8 tilemap.
• map_set : Setup map base pointers and positions
• map_load16 : Load tilemap made out of 16x16 tiles.
• documentation : Document tilemap format

Import the routines described in this document

The current xe1-ap/cyberstick driver is loosely based upon Operation Wolf code ( https://github.com/BlockoS/HuDK/blob/master/include/analog.s )

This document gives more detail https://github.com/AleffCorrea/PCE-XE1AP-ANALOG

• sprite.s
• example/asm/5_joypad
• example/asm/6_sprites

Make a tool to convert TMX files to binary data.

• json import
• tiled parsing
  • json
  • xml (use https://www.msweet.org/mxml/ )
• convert tiles and palettes
• convert tilemap to vdc BAT format
• use external library for cli arg parsing.

Add.

• routines to load a 8x8 font
• use a plain color (eg not color index #0) for font background ➡️ #23
• text printing routines
• display number in base 10 and 16 ➡️ #35
• document:arrow_right: #31
• example(s)

Add routines to clear VRAM.
There may be 2 versions.

1. VRAM offset, word count
2. VRAM offset, words per line, line stride, line count

The current font uses the color index #0 for background.
That will be troublesome for textboxes.

• Backup RAM ➡️ #32
• Memory Base 128 ➡️ #33

The directory is docs/nd/

Add clock routines (get elapsed ms/s/m/h).

Add asm include files and documentation for :

• Ports value (timer, irq).
• Bit fields+masks.

It may not include any routines (maybe just some macros).

Add an include file that maps CD ROM bios functions and the variable defined in the Hu7Cd document.

Add a routine to copy raw data to VRAM.

Add comments to vgmstrip, and documentation to the produced stripped VGM.

vgm samples and routines don't compile with ca65.
There are issues with irq_on, irq_enable_vec and irq_set_vec macros.

The CA65 code is lagging behind!

Add a routine to clear a BAT area. Something like :
print_fill(x, y, w, h, character) or a more general routine vdc_bat_fill(x, y, w, h, tile_offset, palette_index)

Implement text areas in order to clamp, position text.

Create a tool that converts/strip raw VGM files.
Add (or backport) a simple VGM player.

Don't forget it!

Tools needed for HuDK 1.0.0 :

• VGM ➡️ #8
• WAV file
• Image
• Tilemap ➡️ #29

Add asm include files and documentation for :

• Ports value.
• Bit fields+masks.

It may not include any routines (maybe just some macros).

Or move the default 1bpp 8x8 font out of font.inc.

Add a minimal HuCard startup code. This means simple irq vectors.

• pceas
• ca65

Implement basic interrupt handlers.

• Joypad (2 and 6 buttons) with multitap
• Explicit single joypad read (2 and 6 buttons) ➡️ #14
• Analog joypad (:arrow_right: 1.1.0)
• Mouse ➡️ #15 (:arrow_right: 1.1.0)
• Pachinko controller
• Multitap/unplugged controller detection ➡️ #43

Add support for :

• 2 buttons joypad
• 6 buttons joypad
• multi-tap
• mouse
• other (pachinko, analog) ?

Write tutorials and provide examples, maybe a mini-game.

Add routines to display numbers (byte and word) in :

• base 10
• base 16

Tools will need to extract directory name, base name, from filename as long as absolute path.
Unfortunately posix code may not compile under mscv.

So... either code cross plateform file path management fonctions or find a small thrid party that'll do it.

Add asm include files and documentation for :

• Ports value.
• Bit fields+masks.

It may not include any routines (maybe just some macros).

Add mouse routines (documentation).

Add HuCard versions of the bm_ routines of the Hu7 SDK.

There are strong constraints on the font routines.

1. The font must stored as tiles in VRAM.
2. The font is 8x8 fixed sized.
3. The font must match a specific ASCII range.
4. The provided font is made of 2 colors.

Add some pseudo code for variable size or huge alphabet text output.

Update vgmstrip tool and replay routine

Add routines to read a single joypad (2 and 6 buttons version).

Add asm include files and documentation for :

• Ports value.
• Bit fields+masks.

It may not include any routines (maybe just some macros).
