TKA Virtualand is like making themselves kind notorious to its arcade players for making retaining the price of Jubeat Saucer Fulfill for Standard Mode. Standard Mode for that game uses $2 or $2.50. The worst thing that can easily cause the Coin Mechanism problem is the fact that the Course Mode costs $4. The only way to insert credits will be to use the newest local 50-cents coins, not the old ones. Inserting anything else may be bound to cause the mechanical problem in a stupid way and I found a 20-cent coin in the Coin Returner while inserting my 50-cents coins to start the game. It seems that I had to be patient when inserting coins and of course, whoever inserted any other coin than new 50-cents coin must be some kind of a playful vandal. Speaking of vandalism, the turntables for Beatmania IIDX machines at the arcade were vandalized. Nobody knew who the culprit was but we suspected that some Jubeat player was behind that. Even the similar incident at Serangoon Nex TKA arcade happened there as well.
So, I started off in Light Mode just after noticing the number of credits required for Standard Mode as I inserted 4 50-cents coins, not 5. Light Mode is light with 3 songs per run and no Extreme difficulty, Standard Mode lasts 3-5 songs I believe and Course Mode is something like Skill Analyzer from SDVX II and Class Mode from Beatmania IIDX but in different way. Having to test myself with $4 is insane but the super worst thing is the over-popularity of the game. I don't think I can get some chance to play it when it has been occupied with tons of people. The achievements are nothing special like I don't see a better point in unlocking the song at the end of the game. Sure, the achievements can net you additional items needed for the song unlocking portion similar to getting Tran Medals but it is bound to be taking you endless amount of playthroughs compared to Beatmania IIDX where you have 150 Tran Medals to earn. And of course, I'm afraid that I won't be able to complete those game events on time as if the new IIDX sequel will be coming in sooner or later. Maybe a new sequel will arrive in September, October, November, December or even next year, I don't know. By the time the sequel is announced, I don't know if the rest of Tricoro songs will be available in that sequel or not by default like you don't have to unlock them at all.
