i-Singer (Korean version of e-kara) running in MAME with Korean Vol.11 cartridge
The i-Singer, released in Korea by Sonokong is a localized version of the popular e-kara Karaoke system. The Korean version is interesting because it has it's own line of ~16 unique cartridges containing mostly Korean songs, it's also not 100% compatible with the Japanese release as while you can plug the Korean cartridges into a Japanese unit and vice-verse the BIOS ROMs have different graphic resources so the display is corrupt when doing so. 4 Korean cartridges and the base i-Singer unit were dumped, so MAME can now run it. This video shows MAME running Vol 11 from the Korean line-up.
As always the XaviX sound emulation is not the best, as envelopes aren't working, and looping sounds all play as single-shot, so this shouldn't be seen as an accurate portray of how the system would sound (it sounds quite a bit better on hardware than the current emulation, especially for slower songs where there should be lots of held notes)
