tiny viewer for packed resources, that supports chained grouping and packing with RLE/LZ77/Huffman code

Use arrows keys for selecting, entering and exiting files & folders.

See for packer.

Cartridge map memory areas are used for compressed data storage.
Everything is handled by single lua function UNPAK() of <2000 characters long (about 100 SLOC), which supports chained containers of:
- RLE-compressed data
- LZ77-compressed data
- Canonical Huffman Coding-compressed data
- raw data
- folder containers
- pack (array) containers
- text containers
- binary containers
- image containers with custom pallete



NICE! How did you compress those files?


Can it be able to store an audio file and use it as 4-bit sample playback?


Just realized file data is maintained within the map editor. Seems like Drive A starts at map frame 0,0 and Drive B starts at map frame 0,4. If Nesbox were to make MMC plugin support for TIC-80, then we can't waste up the entire map space then!



Packer is written in Python and is avaliable on GitHub (see updated description).
Run 'python' to create sample file. Import it to TIC-80 with "import map" command.
Use UNPACK(0x8000) and UNPACK(0xC000) to browse unpacked structure of produced archives.

Drives A and B are just aliases for TIC-80 memory ranges started at 0x8000 and 0xC000. Actual API does not require to mount any drive letters, it's just a familiar metaphor for data collection =) You can set any other addresses as well, I just wanted to demonstrate that I can handle several archives.

Map areas is 0x8000~0xFF80. So, I selected A and B to split it into 2 almost equal parts.
Actually you can store archives almost anywhere in TIC-80's memory, including cover image (0x0000~0x3FC0), strites sheet (0x4000~0x8000), and sound area (0xFFE4~0x13FFC). I started with map area because it is easily imported "as is". Maybe I'll add some code to produce disks in sprites.gif and cover.gif as well.

Right now there is no code for audio packing and playback. However, if you have a music/sound composed with TIC-80, with some skills it is possible to have bytes of those compressed and switch tracks by unpacking them into sound memory. It's an interesting idea, I may want to try it as well =)


Where did you find those kawaii images?

i do like the hentai


Those pictures are really inappropriate.


why is there hentai in B:
