ROM set changed: no
0.106-0.272: youjyudn - "Youjyuden (Japan)"

MAME History:
- 0.106u12: MASH added PLD ($0 - yju_b-pal16r4a-8m.pal) to Youjyuden.
- 0.126u5: Fabio Priuli changed a lot of input related things in IREM M10->M107 boards. First of all, moved input definitions from drivers\m92.h to include\iremipt.h and removed completely drivers\m92.h (which only contained those definitions). Added more common inputs to iremipt.h and started to use that file in m62->m107 instead of local #defines. Finally, added DIP locations to all the games in m62->m107 which were missing and it implemented coinage mode 2 through dipconditions in the drivers which didn't support it.
- 0.234: Use raw parameters for screen [AJR]. Changed VSync to 55.017606 or 56.338028 Hz.

Resolution, 0.106-0.233: 256x256 @ 55.000000Hz

Service Mode:
Typical Irem M62 system.
Service Mode reflects the local configuration after playback ends, not the recording. Service Mode is then accessed by enabling the DIP Switch which can be toggled with the Service Mode Button (F2) followed by a reset thus cannot be recorded in an INP. An initial ROM/RAM test screen appears which can be progressed using P2 Start button. Navigation is with P1 Up and Down. Selection with P1 Start button at the top level and P2 Start button to exit sub-sections.
