2015.10.02 截圖請至來源處瀏覽 o'_'o Emu-land.net once again accidentally provided some interesting artifact. There are two russian games on partially working reset-based UNROM multigame cart. Luckily, the first one I dumped already some time ago, but the second one was a way better. The russian translation of "The Little Mermaid" was better than most other older or newer translations, because it has translated title screen as well as most of the texts. There are no authors copyrights left inside, but we may say for sure, they aren't "Snake" or "Elektronika", because they usually put it's own telephone numbers and advertisings inside. So, judging from the PCB, there must be at least two more games on board, and they may be the russain ones and may be even unknown! Thanks to asdendy for providing this cart for me to dump and repair. Unfortunately, two other games are just regular english versions of the known dumped games, but at least one "The Little Mermaid" Malen'kaya Rusalochka (R)[!] http://cah4e3.shedevr.org.ru/dumping/2015/Malen'kaya_Rusalochka_(R)[!].rar As I promised, here is the main dish, thanks to famiac for providing these carts! First, here is the rehacked and "inproved" version of Dr.Mario with number II on the title. Actually, this is 2-in-1 cart (precisely 1+8-in-1). One half it's mostly the same Dr.Mario with graphics similar to the regular version, but the second part is 8 different graphical skins to the regular game, ripped partially from Wario's Woods or Little Nemo or other games and partially is original. The pause screen contains some authors copyrights, a name of company "ES INC" and year 1996. There is an original bug in his game. Both title screens will hang when attempting to start a demo sequence, just like the original version does. This happens on the real console and in emulation, so maybe there were something that autohors overlooked. UPD 31.08.15: Shame on me! So hurry to dump and release and I didn't checked it carefully. Actually, nothing really bad, but previous dump was overdumped with garbage. It seems that this mapper was designed for a simple multigame cart with hardware menu selection. Sometimes carts do this using manipulation with address lines, which is enabed with some registers bit. This time, this cart clears lower 4 bits of address line if particular bit is set. So we have a series of repeated byte of every 16 data block. This game seems doesn't use this feature at all, so nothing is changed in emulation. Even if it would, nothing should happens too. With current mapper code and dumped garbage data, this cart woild be emulated exactly the same way as on hardware. Now I removed the overdumped data, fixed the mapper implementation and put all this here as a second option. UPD 08.09.15: Accidentally after some forum discussions and careful disassembling the code I realized that the HW switch mentioned in 31.08.15 update actually used in this game. So, this cart contains as much as 3 different games! In addition to the firs one we have seen, the second one is called "Magic Sprite" and has only 8-in-1 mode but with player number selection on the game mode selection screen. The second one called "Doctor Mary 9-in-1" and contains a menu with all 9 games including a hidden one (select the middle-bottom game in any 8-in-1 modes, press Up, then Start, thanks adrian09_01 for info!). So if we summing all this games, we have 1 + 8 (+1) + 8 (+1) + 9 = 28 games in total! But they are the same. ;) Most likely, there are two other carts may exists with the rest of modes enabled by default with HW switch. I added the HW switch selection to the FCEUmm on the particular page on this site, you can try to switch just by press the Reset button one or two times. Also there are some new screenshots added here.
