Releases

Library

A fourth view, List: a table with title, year, developer, publisher, players, play time
and last played; click a header to sort.
Play time and history: every session is recorded and shown in the list, on the game's
info sheet, in the game's History… and in File › Play history….
The covers are 20% larger and spread over the whole width of the window, with no empty
strip on the right.
Your own box art is also used on the info sheet and in the "Game cover" frame.

Interface

Error report: if the program crashes, it writes a report in the crashes/ folder of its
settings folder, and the next start shows where it is, to attach to a bug report.
The window never opens bigger than the screen.
Copying text works (it did nothing).
"Open last game on startup" is off by default.
Quick menu: narrower, and its button hints in two lines (they wrapped in the middle).
Removed the Console frame: the drawing did not look like the real PV-1000. The TV and
game cover frames remain.

Documentation and validation

The README is short; the rest is in docs/ (manual, hardware, compatibility, accuracy,
architecture, libretro core, lessons, references), in English, Portuguese and Spanish.
reference/: the MiSTer core simulated with Verilator and compare.sh, to repeat the
validation with your own ROMs.

First release. A Casio PV-1000 (1983) emulator in Rust, reimplemented from the MiSTer core.

Emulation

Runs all 13 released cartridges and 26 homebrews: Inufuto's 22, plus PVong, Simon,
Demônios and the PV-1000 Control Test ROM.
Two models (Emulation › Model):
- MiSTer core (validated, default): picture and RAM identical, byte by byte, to the
  simulated MiSTer core in every game tested;
- Real hardware (NESdev / MAME): the console's timing (288 × 262 at 59.299 Hz, the
  CPU stopped while the picture is drawn), interrupts, joystick matrix with its
  electrical delay and full FE/FF ports. It matches 11 measurements made on two real
  consoles (Par's test programs) and the photos of lidnariq's test ROMs.
Sound as on the real console: one octave below the MiSTer core, per-channel
volumes, port FB (mute, XOR mode) and high-pass filters.
TV picture option: 26-line border and 48:35 pixels.

Interface

Library with box art, title or gameplay images, search and info sheets; F5 rereads the
ROM folder; a welcome screen with links to free games on first run.
Save states (9 slots with thumbnails), rewind, fast forward, GIF and MP4 recording.
Debugger (RAM, tiles, CPU, video, sound, ports) and cheats (RetroArch .cht format).
Controller navigation, quick menu and couch mode: Home/Guide or Select + Start (held)
open the menu; couch mode is fullscreen with no menu bar.
Frames (TV, console, game cover), scanline and CRT filters.
English, Portuguese and Spanish; more languages from a JSON file (Help › Language / Idioma ›
Export translation template…).
Settings and data in one folder, ~/.config/mil_capivaras/ (%APPDATA%\mil_capivaras\ on
Windows); Emulation › Folders… opens, changes and resets each folder (save states,
cheats, own box art, languages, screenshots, recordings), moving the files along;
screenshots and recordings default to the Pictures and Videos folders.
Your own box art in the libretro-thumbnails layout, ahead of the downloaded ones.
Portable mode: with a portable.txt next to the program, everything goes into a
mil_capivaras_data/ folder next to it, with relative paths (USB sticks).

Downloads

mil-capivaras-0.9.0-linux-x86_64.AppImage: Linux x86-64 (glibc 2.27 or newer); the
