    As you may know, only some e-Reader cards were released in the US. Caitsith2 encoded most JP-only cards to US format but I noticed the demo cards are missing from his site (or at least I haven't been able to find them): http://caitsith2.net/ereader/sma4.htm
    So I took onto myself to write a small program to convert those with my limited programming skills. Credits to caitsith2, I just adapted his checksum calculation code.

    Demo cards (No-Intro set), ones marked with "USA" were released in the US
    Series 1    07-E001    1-1 Fast Clear                  USA

    Series 1    07-E007    3-8 Hidden Toad House           USA
    Series 1    07-E008    4-2 Hidden Toad House           USA

    1. Download nedcenc.exe from http://www.caitsith2.com/ereader/tools/, and sma4_regcon.exe from attached files (source code included)
    2. If in raw format, decode the card
    nedcenc.exe -d -i JP_card.raw -o JP_card.bin
    3. Region convert the card
    sma4_regcon.exe JP_card.bin US_card.bin
    4. Optional: convert back to .raw
    nedcenc.exe -e -i US_card.bin -o US_card.raw
    Or use the .bat file provided to batch convert:
    sma4_regcon.bat "path/to/cards" 
    - All the JP-only demo cards converted and tested on no$GBA
    - Frog Suit card works converted, but has a few bytes difference with the official US card. Possibly others are the same.

    How to scan: (no$GBA)
    0a. Download e-Reader save with SMA4 data: www.zophar.net/download_file/20656
    0b. Configure no$GBA settings and save
    0c. Rename e-Reader save to match eReader rom filename
    1. Open SMA4 rom in no$GBA
    2. Open e-Reader rom, selecting 2nd machine in Open dialog [only works if eReader is on 2nd machine]
    3. Scan card when prompted (first time it will open a new window, afterwards the card stays loaded, so change it before scanning in-game)

    As a bonus I have included snapshots of all the demo cards, you need to load the correct ROMs as instructed above or no$GBA will crash:
    Super Mario Advance 4 - Super Mario Bros. 3 (USA) (Wii U Virtual Console).gba [D4C13AC3]
    e-Reader (USA).gba [8B27CD67]

    Great to see someone taking the time to create such tools :)
    Do you think it works with all cards? (Even though most if not all are available online)

    You mean all non-demo cards? If so, it should, but I only tested the frog card.
    If you mean all e-Reader cards, then no. Only SMA4.

    I remember buying like all the nes packs, makes me sad for some reason. Were they expensive?

    Oh my gosh, thank you so so much for having written this Checksum program!!

    THIS was the missing ingredient I needed for translating ALL of the unreleased SMA4 e-reader card files into English.

    I just made a thread over in the "GBA Game Development" board, detailing my procedures, as well as featuring downloads to everything. Go ahead and give it a look.

    UPDATE: It looks like I won't be able to post that thread for another 24 hours. Please be patient and bear with me. It will be posted tomorrow.
