the 4.50 version that has Virus is the "base" (1st revision) and doesn't work without the update (2nd revision GXX10JPN27) .. the final dump link is available on discord .. if you use 1st revision you get this error (updater) :

The games are fully functional and safe, Chameleon RX-1 is a dumped system also in Mame (wip)

all xboost are 4.50 due to the "allnet version number" but the actual game versions are from 1.01 - 1.27 (1st xboost dump that appeared public was the base version which cant be played)

the right one is GXX10JPN27

Wangan Midnight Japan (wmn1-a) it's region locked, you need a working export dump (wmn2-a)

JP3 and all the Konami Viper games, despite not having major developments and lots of IRQ's problems, also run on the current versions of Mame

Byon Byon HD patched 1920x1080 Fullscreen gs-system.dll

I believe this chinese version should be 1.12

Play! 2x6 emulator is still young, so games support is about 50%, some need patches, some need dongle fixes, but there is enough on the discord channel to get info and get support

there are 23 pages of posts and explanations on how to convert a chd, create a chd from an img and deal with a .defs, I highly recommend learning the basics and understanding that the name of the .bin and .chd doesn't matter, but it is important that they coincide with the name associated with the .arcadedefs here you can find media ID : https://github.com/mamedev/mame/blob/master/src/mame/namco/namcops2.cpp and in the specific case for Idol Master the name is NM00022 IDM1-HA (HDD).chd

you need this build -> Play! v.061-33-g1a51df81 - Jun 26 2023

idolm.arcadedef

.chd it's on mame : https://pleasuredome.github.io/pleasuredome/mame/

all Taiko serie have been dumped, look my post :

Taiko series added Play! v0.60-91 https://gofile.io/d/Ci50Mv

This is an "arcadish" PC version but I think (hope) good enough to play. I made some changes to the HUD to make it as faithful as possible to the arcade version (free play). Just run the .exe to set resolution & screen mode and mouse left button to play. Link: aHR0cHM6Ly9nb2ZpbGUuaW8vZC9nZXFwS0c=

For those who have problems related to crashes when starting the game, here is the procedure : Open Command Prompt as administrator. Type or Copy and paste the command below and press Enter Reg query "HKLM\SOFTWARE\Microsoft\Net Framework Setup\NDP" /s Check which and how many .NET Framework versions are present and, if necessary, add the missing versions. This is a list of recommended versions to have on windows 10+ framework.rar

I honestly hadn't tried it yet (I asked Argon for a re-compiled version higher than the 2.0 framework used for the plugin), but now I'm going home and trying it right away

maybe it depends on the chipset, it does the exact thing on intel i9 11900k (only and exclusively on that PC, perfectly working on 3 others with same mobo/gpu/memory/os but different cpu) DS & Mouse input
