Starting the Project

The project initially started out with a desire to be able to scan my e-amusement pass on my PC when I’m playing chunithm on my home setup. I bought a smartcard reader hastily without checking that it had FeLiCa support, then finally settled after reading into it on the acr122u.

Once I had a smartcard reader that could actually recognise the AiC card, I had assumed I’d be able to build one of the existing projects out there without issue and use it, however the two projects I could find (raviddog’s aimeio-pcsc and AkaiiKitsune’s aimeio-cardreader) both had their issues with my setup, so I turned to forking aiemio-cardreader.

Yhumi/aimeio-cardreader

Existing as a fork of AkaiiKitsune’s work, it implements the following extras on top of the original repo:

raviddog’s FeLiCa Serial -> Mifare Access Code conversion via aimeio-felicadb.txt
A better scanning system/timeout system that acknowledges when the game should have read the card, stopping any erroneous double-scanning issues.

Building the project

Building (on linux) is as easy as installing meson & ninja, then running the following commands:

meson setup --cross cross-mingw-64.txt b64
ninja -C b64

This should output src/libaimeio.dll and src/aimetest.exe, rename libaimeio.dll -> aimeio.dll and you can use aimetest.exe to check functionality.

Using the project

Copy (lib)aimeio.dll to your chunithm/App/bin/ folder, update segatools.ini to add the configuration lines:

[aimeio]
path=aimeio.dll    ;Path to aimeio.dll
scan=0x0D          ;Sets the key which will be used to insert a card in game. The default is 'Return'

;Everything below this line is optional.

readerOptional=1            ;Make reader optional, so that you can still use the keyboard
readerName=ACS ACR122 0     ;Manually select which reader to use
disableBuzzer=1             ;Disable the buzzer
;aimePath=""                ;Manually specify an aime.txt file
;felicaPath=""              ;Manually specify a felica.txt file
;debug=0                    ;Display function calls

Then create your aimeio_felicadb.txt and aime.txt, and have fun! ♥

aimeio_felicadb.txt format

<felica1> <access_code1>
<felica2> <access_code2>
12345678 1234567890

aime.txt format

<access_code1>
<access_code2>

Provided as-is, build it yourself, modify freely, have fun (and let me know if you improve it) ♥
