🔊 Audio Improvements

The PicoMEM 2 significantly upgrades its audio capabilities, allowing all emulation modes to run simultaneously (e.g., you can run General MIDI + GUS at the same time in DOOM).

  • Onboard Dedicated DAC: Features a premium PCM5102 DAC with optimized 4-layer PCB routing and an onboard 3.5mm audio jack for pristine sound quality.

  • Hardware-Assisted Sound Blaster: Sound Blaster emulation now utilizes hardware DMA, drastically improving game compatibility.

  • Gravis UltraSound (GUS): Native GUS support added, complete with 1MB RAM, DMA, and IRQ allocation.

  • MPU-401 / General MIDI: Implemented via a modified, high-quality TinySoundFont library.

  • Stereo OPL3: Audio output now generates true Stereo OPL3 instead of standard OPL2.

🔄 Firmware & Compatibility Updates

(Note: These software-driven updates are also backward compatible with PicoMEM 1)

  • Expanded Controller Support: Native support for DirectInput, PS4/PS5, and Switch/Switch 2 controllers via joypad-os.
  • Variable Disk Geometry: Added support for custom disk geometries using an accompanying .chs text file (formatted as imagename.chs).
  • Compatible with the latest tools by FreddyV - see this github page for downloads and getting started information

 

📋 Core Features Summary

picovox is a sound card for parallel port, that can emulate several sound devices :
  • Covox
  • Stereo-On-1
  • FTL Sound Adapter
  • Disney Sound Source
  • OPL2LPT
  • OPL3LPT
  • TNDLPT
  • CMSLPT
The picovox project is designed by Jan Samek. 
This serdaco version of the PCB is developed in special agreement with Jan Samek.

picovox PCB specs :
  • dimensions :  54mm x 47mm
  • parallel port connector
  • USB-C power connector
  • 3.5mm stereo line out 
  • optional 3d printed high quality enclosure
For up to date information, check out the pivocox open source project here

You can select the emulated device using pcvx.com

How do I use it?

You just need to plug your picovox into any LPT port of your computer, plug in the power to the USB-C connector and your favorite pair of speakers into the audio jack. In case of Covox/FTL/DSS/Stereo-On-1 you can use them right out of the box. In case of OPL2LPT, TNDLPT and CMSLPT, you can use them in the same way as the listed devices; either with games with native support, or load their drivers/patches. You can switch between modes via a tool for DOS called pcvx.com :

How to use PCVX.COM ?

You have to copy the pcvx.com file to your DOS computer.

You can download the latest version from RELEASES.

The usage is as follows:

PCVX [PORT] MODE [DEVICE]

PORT

You may specify the port by using LPT1, LPT2, or LPT3, depending on where your picovox is connected. If your picovox is connected to an LPT port at a non-standard address, you can use ADDR0x378 where you replace 0x378 with your base address (where data pins are set). The status register is base + 1, and the control register is base + 2.
 

MODE

Option Device Description
INIT ❌ Initializes the port for picovox use.
STATUS ❌ Prints the status of the picovox device.
SET ✅ Sets picovox to the specified emulated device.
HELP ❌ Prints available commands with descriptions and use examples.
LIST ❌ Prints all the supported devices you can use in DEVICE.

DEVICE

Mandatory argument for SET. Specifies the emulated device.

 
Option Description
COVOX Covox Speech Thing/Intersound MDO/Generic 8-bit DAC
OPL2 OPL2LPT, Adlib compatibility with ADLiPT/adpatch
OPL3 OPL3LPT, Adlib/SoundBlaster compatibility with ADLiPT/adpatch
CMS CMSLPT, GameBlaster compatibility with CMSLPT
TND TNDLPT, Tandy/PCjr compatibility with TNDLPT
DSS The Disney Sound Source
STEREO Stereo-on-1 by Mark J. Cox.
FTL FTL Sound Adapter supported by Dungeon Master.
SID SIDLPT, Innovation SSI-2001 support with patches. Not implemented yet
MP3 MP3 decoder using specialized program. Not implemented yet

Example usage

PCVX LPT1 SET COVOX – Sets picovox on LPT1 to Covox mode.

PCVX ADDR0x3E8 INIT – Initializes picovox on address 0x3E8.

PCVX STATUS – Shows current status of picovox.

PCVX HELP – Prints help.
