# Notice: authors and licenses

## ITOSM Korean edition (2026-11-10)

Modified from mameise/Paramix-Studio commit
`675b904ab1c8a9086b977a82cbc47cd0c319187f` (version 1.7.4).
Changes: Korean web translations, optional Korean A+C menu, Korean font rendering,
menu language detection, compact layouts, and self-hosted Docker packaging.
The original English device-menu binaries are retained. Korean device-menu builds
have PC-only synthetic checks; no physical-device validation has been performed.
The Korean UI uses English for emulator settings that only support English/German.
Galmuri9 by quiple is used under SIL OFL 1.1; its source and license are in
`third-party/`. Generated font data is marked as a subset.
The modified program remains GPL-3.0-or-later. See README.ko.md for build steps.

copyright and licenses stay in force; the files keep their original notices.

## TamaEmu (`emu/`)

- **tamaemu** by maragotchi, https://github.com/maragotchi/tamaemu,
  GNU GPL version 3 (copy in `emu/LICENSE` and `emu/src/core/LICENSE-tamaemu`).
  The emulator core in `emu/src/core` is derived from tamaemu. The layout of
  the download content stores and the routing of download records
  (`src/emu.js`, `emu/src/tools/dlc.py`) follow tamaemu `tools/dlc.c`.
- Changes for this project: a slim core for the Paradise without an operating
  system, the JIT translator from S1C33 to Thumb-2 (`tc_jit.c`), the Paradise
  host (`emu/src/emu`), the launcher stub and the ROM packing. Same license.
- The S1C33 instruction decoding follows the SLEIGH definition by GMMan,
  https://github.com/GMMan/s1c33_sleigh.

## T7Emu (`t7/`)

- The 6502 core in `t7/src/core` is a C port of the JavaScript emulator
  **tamago** by asterick, https://github.com/asterick/tamago, which its
  package declares under the BSD license. The port comes from the T7Emu app by
  mameise. The note in the source files stays.
- Changes for this project: a fast run loop (`t7_run.inc`), a build without C
  library, the Paradise host (`t7/src/app`) with screen, settings menu, clock
  and save. The 20x20 icons were drawn by mameise for the T7Emu ESP32 version.
- No ROM of the Tama-Go or of a figure is in this repository.

## T18Emu (`t18/`)

- The ARM7TDMI core and the TG18 SoC model in `t18/src/core` come from the
  T18Emu app by mameise.
- Changes for this project: a slim core for the Paradise, idle round skipping,
  the translator from ARM and Thumb to Thumb-2 (`t18jit.c`, `t2enc.h`) and the
  Paradise host (`t18/src/app`). It uses the Paradise hardware layer of TamaEmu
  (`emu/src/emu`). Same license as the rest of this repository.
- No firmware of the Meets or On is in this repository.

## DOOM (`doom/`)

- **DOOM** source code by id Software, released under the GNU GPL.
- **PrBoom** (based on BOOM, LxDoom and LSDLDoom), Copyright (C) 1999 id
  Software, Chi Hoang, Lee Killough, Jim Flynn, Rand Phares, Ty Halderman;
  (C) 1999-2000 Jess Haas, Nicolas Kalkhof, Colin Phipps, Florian Schulze;
  (C) 2005, 2006 Florian Schulze, Colin Phipps, Neil Stevens, Andrey Budko.
- **GBADoom** by doomhack, https://github.com/doomhack/GBADoom, with additions
  by Kippykip.
- **nRF52840 Doom** by Nicola Wrachien (next-hack),
  https://github.com/next-hack/nRF52840Doom.

  These are licensed under the GNU GPL version 2 or (at your option) any later
  version (copy of version 2 in `doom/LICENSE-GPL-2.0`). The Paradise port in
  `doom/src/pdoom/dev` is by mameise under the same terms.
- **MCUDoomWadUtil** by Nicola Wrachien, based on GbaWadUtil by doomhack,
  GNU GPL version 2. It is used as a separate program: compiled to WebAssembly
  (`doom/mcuwad.wasm`, source in `doom/src/wasm`, command line version in
  `doom/src/umwandler`) and only fed with the WAD file chosen by the user.
- **printf** by Marco Paland (PALANDesign Hannover), MIT License, notice in
  `doom/src/pdoom/plat/printf.c`.

No WAD file and no DOOM game graphics are part of this repository. The user
brings their own WAD; the Studio converts it in the browser.

## V1Emu (`v1/`)

- **TamaLIB** by Jean-Christophe Rona, https://github.com/jcrona/tamalib,
  GNU GPL version 2 or (at your option) any later version (copy in
  `v1/src/core/LICENSE_tamalib`). The core in `v1/src/core` is TamaLIB with
  changes for the Paradise (decode table, saving the CPU state, the Digimon's
  LCD, keys, buzzer and contact P20).
- The Paradise program (`v1/src/app`) and the icons are by mameise.
- No ROM of a Tamagotchi or Digimon is in this repository.

## V3Emu (`v3/`)

- **BrickEmuPy** by azya52, https://github.com/azya52/BrickEmuPy, released
  under **CC0 1.0 Universal** (public domain dedication: the author gave up all
  copyright, the work may be copied, changed and used for any purpose without
  asking and without credit). Credit is given here anyway.
  From it come: the Sunplus SPLB32 core (`cores/SPLB32.py`, the 256
  instructions translated to C by `v3/gen/py2c.py`, the rest by hand), the
  HT24LC08 EEPROM (`peripherals/HT24LC08.py`), the infrared byte link
  (`peripherals/CON_V3_IR.py`) and the positions of the 32 x 30 dots and the
  ten icon segments of the Connection V3 face (`assets/Tamagotchi_v3.svg`,
  only the positions, in `v3/src/core/v3lcd.inc`).
- The C port, the timer and halt speedups, the Paradise program
  (`v3/src/app`) and the icons are by mameise; with the rest of this
  repository under the GNU GPL version 3.
- No ROM of the Connection V3 is in this repository.

## GBEmu (`gb/`)

- **Peanut-GB** by Mahyar Koshkouei, https://github.com/deltabeard/Peanut-GB,
  **MIT License** (the notice is at the top of `gb/src/core/peanut_gb.h`).
  Parts of it come from SameBoy by Lior Halphon (MIT), marked in the file.
  Changed for the Paradise: the ROM is read straight from the flash window
  (marked "Paramix").
- The Paradise program (`gb/src/app`) is by mameise; with the rest of this
  repository under the GNU GPL version 3.
- No Game Boy game is in this repository.

## ArduboyEmu (`ab/`)

Own code (mameise), no code of other emulators. The CPU was checked against simavr (GPL) on the PC only; simavr is
not part of Paramix Studio. Arduboy is a trademark of Arduboy Inc.

## PokeMiniEmu (`pm/`)

- **PokeMini** by JustBurn (Team Pokeme), libretro version https://github.com/libretro/PokeMini (commit 132111b),
  **GNU GPL version 3 or later** (copy in `pm/src/core/LICENSE_pokemini`). The core in `pm/src/core` (CPU, PRC,
  LCD, timers, IRQ, I/O with the EEPROM, sound) comes from it, with the **FreeBIOS** (Team Pokeme, in `freebios.c`).
  Changed for the Paradise: `pm_glue.c` instead of PokeMini.c (no files, no colour PRC, the cartridge read from the
  flash window), the LCD read by the program for the shown frames (`PM_FASTLCD`), small stubs (`pm/src/stub`).
- The Paradise program (`pm/src/app`) is by mameise; with the rest of this repository under the GNU GPL version 3.
- No Pokemon mini game and no Nintendo BIOS are in this repository.

## Wolfenstein 3D (`wolf/`)

- **Wolf4SDL** by Moritz "Ripper" Kroll and others, maintained by KS-Presto,
  https://github.com/KS-Presto/Wolf4SDL (commit dc8b250), based on the
  Wolfenstein 3D source code by **id Software** (1992). Wolf4SDL offers the
  original source license (`wolf/src/w4/license-id.txt`) or the **GNU GPL
  version 2 or later** (`wolf/src/w4/license-gpl.txt`); used here under the GPL.
  John Carmack confirmed the GPL relicensing of the Wolfenstein 3D source.
  The OPL emulators of Wolf4SDL (MAME license) are not used.
- Taken: the game parts (`wolf/src/w4`, changes marked `PARAMIX`). New for the
  Paradise (`wolf/src/pmx`, `wolf/src/dev`, `src/wolf.js`) by mameise; with the
  rest of this repository under the GNU GPL version 3.
- No game data of Wolfenstein 3D (maps, graphics, sounds) is in this repository.

## Formats and protocols

- File formats of the Paradise flash (archive, sprites, scenes):
  https://github.com/GMMan/tama-para-research by GMMan.
- The rest (settings block, ID pages, field slots, app loading and the PAU1
  flash protocol in `flash/`) was worked out for this project.
