Flash Cart

Atari Lynx Flash Cart

Been waiting for this one for some time. This is a great microSD to Atari Lynx flash cart made by RetroHQ and there is a wait list for the at the moment that he’s catching up on pretty quickly.

This cart will work in the model 1 & 2 lynx handhelds. He makes a case/shell for it but when fitted with the shell it will not fit in the model 1. I opted for the non shell version since I own both models and not sure what one will be used more with this cart.

RetroHQ tossed in a 1gb SD card that he had the latest menu software on it. I tossed a couple roms on it to test with and it worked with no issues at all. I did find out that the sound is out on my model 2 Lynx… so time to fix that.


With the Sony Vita getting a full blown CFW (HENkaku Enso) I now have a need for more storage space more than ever. The Vita has an overpriced proprietary memory card that only goes up to 64GB. With the vita game sizes, we need the ability to have larger capacity cards. In comes the SD2Vita PCB. This PCB gives you the ability to use a microSD card and insert it into the Vita game card slot. You then need to load a driver with HENkaku Enso to mount this as usable storage. A very easy mod and well worth the effort.

I ordered the PCBs from PCBWAY and it cost about $15 shipped for 5 PCBs. I then ordered the micrSD slots from Amazon for about $2.

Harmony Cart

Information: Taken form the Harmony manual.

The Harmony cartridge is a programmable add-on for the Atari 2600 console that allows you
to load an entire library of games into a single cartridge and then select which title you want to
play from a friendly, on-screen menu interface. It features an SD card interface, making it simple
to access the large library of Atari 2600 software. The Harmony cartridge supports almost all of
the titles that have been produced for the Atari 2600. It can also be used to run your own Atari
2600 game creations on a real console. The Harmony cartridge is flash-upgradeable, and will be
updated to support future Atari 2600 developments.

I have not had time to play around with it yet but soon enough I will be playing some combat on a 13″ tube TV and loving every minute of it.

Flashboy +

Here is a flash cart for a system that does not get that much attention. This is for the Nintendo Virtual Boy.

This is a standard Virtual Boy cartridge with a mini USB port on it. This is for writing roms to the 16 MBits (2 MBytes) internal flash memory.  The down side is, it only holds one game at a time. This is a bit of a let down since I am so used to the Everdrives carts which are some sort of SD/microSD and can hold a whole library. To load a game to the Flashboy + you will need to use the supplied loader software and connect the mini USB cable to your PC. This is a pretty simple & straight forward task.

The cart does not have a backup battery so games like Galactic Pinball and VB Wario Land are playable, but can not take advantage of the battery.

Normally I open up the carts to take pictures of but I am not wanting to break the superglue that holds this 3D printed case together. I will will pop it open in the future and update this post.

I got frustrated with wanting to play some SNES games and finding out that my Super Everdrive could not play them due to the needed enhancement chips. Commence ordering the SD2SNES from StoneAgeGamer.

Features list taken from StoneAgeGamer

  • SD/SDHC/SDXC support (tested up to 64GB; no exFAT support so SDXC cards must be reformatted using FAT32)

  • Directories are sorted automatically, no need for FAT sorting tools
  • High resolution menu (512×224) for adequate display of long file names
  • Real Time Clock
  • Supports ROM size up to 128MBit (96Mbit actually implemented)
  • Automatic near-time SRAM saving to SD Card (while the game runs). Some limitations apply:
    • near-time saving is switched to periodic saving when a game is found to use the SRAM as work RAM.
    • Automatic saving is disabled when MSU1 is used. SRAM is saved on reset.
  • Enhancement chip support (see below for implementation status)

  • Auto region patching: eliminates “This Game Pak is not designed…” messages regardless of 50/60Hz setting


Everdrive GBA

This is to replace my loved SuperCard MiniSD. Many hours of Advanced Wars have been played on my SuperCard over the years. Recently I wanted to update the ROMs on my MiniSD and found that the software was just as wonky as I remembered it and had trouble with some of the later GBA games. It all came down to playing Final Fantasy 6 and putting in 6 hours and finding out my save was corrupted to help push me to the Everdrive GBA. The Everdrive GBA is dead simple to get up and running, just add games to a MicroSD and boot. I know this is like beating a dead horse but I wish the size of the cart was of a standard GBA game like my SuperCard… but that said, this thing is awesome.

Features taken from StoneAgeGamer

  • 256Mbit PSRAM (32MByte) ROM memory
  • 1Mbit SRAM (128KByte) save memory
  • Real-time clock support
  • Low power consumption
  • SD, SDHC and SDXC cards are supported. Tested with micro-SD cards up to 64GB
  • FAT32 support
  • Supported with GameCube Player, Super Retro Advance and other GBA accessories


SuperCard MiniSD (GBA)

This was the first GBA flash card I got and I bought it the month it was released. It served me well all these years even with all the software quarks. The glaring downside of this cart was the fact that you had to use their software to transfer games to it. The software would inject a temporary save state and any cheats you might want to enable. This sounds awesome but I would constantly get errors from the software on so many ROMs. Sometimes they would work fine even with the errors but most would not. So it was a tedious process making a card of all “working” games. With this card now being over 11 years old, it has not really stood up well against cards like the Everdrive GBA but for its time it was amazing. The way this card is a real winner is by the fact that its the size of a GBA game and does not stick out at all in the handheld. This can not be said about the Everdrive GBA.


  • Compatiable with GBA/SP/GBM/IDS/NDS/NDS Lite.
  • Built in emulators include emulators for the NES, Gameboy, PC Engine, Sega Master System and the Game Gear
  • Supports Real Time Save functions.
  • Supports compressed game files (Compress option in software)
  • Possible to store up to 32Gbit (4Gbyte) on one single SD card.


FAT File Syystem?

Yup, this device only supports FAT/FAT16 file system. That mean no MiniSD cards over 2GB are supported.

When using GBA files:

  • L + R + B + SELECT brings up REALTIME SAVE menu
  • L + R + A + SELECT brings up SC NORMAL SAVE menu
  • L + R + START + SELECT resets to the main menu

Keeping Save Files to MiniSD:

In order to keep your GBA game saves you must reset to the MAIN menu, scroll right to the SAVE menu, locate the game file you want to save, press A to bring up SAVE prompt, and select “YES” to save to SD.


For GBA games, this is not drag-and-drop solution, you can’t just copy-and-paste these games to the MiniSD and play, the games must be “patched” first using an “outdated” piece of software. For NES/GB/GBC/SMS games you can copy-and-paste normally, without patching.
