i-Singer (Korean version of e-kara) running in MAME with Korean Vol.14 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 14 from the Korean line-up, which appears to be aimed at kids, with all the songs being incredibly short.
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)
