25th Anniversary!!! 3 prototypes, 1 unreleased, 188-in-1 multicart, 2 Brasilian variantsPosted: Sun Mar 27, 2022 7:55 pm
Today is SMS Power! 25th Anniversary!!
Perhaps at this point that we are the oldest independent internet website being still alive and kicking? Who knows!
Let's get thing rolling!
"AIMO" Prototype of Psycho Fox for the Master System.
First spotted in early magazine previews and reviews, the infamous "AIMO Logo" version of Psycho Fox was finally found after 33 years!
Partly developed by Vic Tokai (see thread) much of the development story for this game is still unknown.
Amusingly, the cult credit roll of this version feature a different face for "The Rich Man". Perhaps this was the top person of AIMO (or Vic Tokai) later replaced by Sega's one?
An even earlier prototype of Basketball Nightmare for the Master System. Exactly last year we released a Basketball Nightmare prototype. Then in October we obtained a rare development board from Japan which hosted 3/4 of a final retail build of Basketball Nightmare. Then in December we found yet another prototype of the game, this time much earlier.
Something quite special about this version is how it gives an insight into the programmers experimental and having fun. The credits sequence of this version display names in 3d wireframe! Kudos to NKOICHI for this surprising feat!
Watch a recording of the ending sequence here:
Next we have a surprising "Rolling demo" cartridge of Golden Axe which was exhibited at CES. In the vein of the earlier demos we've uncovered (such as Super Basketball) this is a non-interactive looping demo designed to attract bypassers. Except this one goes *BAM*:
Watch a recording of the rolling demo here:
Unreleased Poker Face Paul's Cribbage for Game Gear. This was actually posted by programmer Matt Taylor earlier this year (along with sources) but we're putting it in the news to attract visibility. The game was seemingly fully developed but unlike the 4 other card games from the Poker Face Paul's series, this one was cancelled. Presumably because the rules of Cribbage appears to be insufferably complicated? :) Who knows.
Not done yet! For the first time ever we are releasing a bootleg multi-cart: [Game Mo-eumjip 188 Hap (게임모음집188합) for the Master System / Samsung Gam*Boy. Back around August Benjamin Sittler and I sat together to start identifying, reverse engineering and emulating several of the multi-carts that have been released in Korea. We are not done with the work yet but decided to release a first one today. This cartridge hold a whooping (PROBABLY NOT) 188 titles mostly based on MSX1 titles, with some Korean hacks and possible exclusives. Please help us build a listing and complete the huge Screenshots page (added screenshots for 40 games so far).
As of today this requires the latest WIP version of MEKA available here: https://github.com/ocornut/meka/releases/tag/meka-20220327. Other emulators will probably add support for this soon.
Finally we have two long-awaited Brazilian releases which unforgivably got stuck in a blind spot of our release queue for a long while. The Brazilian 3-in-1 Game Box Série Esportes containing Great Volleyball, Super Futebol II and Wimbledon actually carries 2 unique dumps that are different from the known existing one.
Super Futebol II for the Master System, translated version from Game Box Série Esportes cartridge. This is actually a DIFFERENT ROM than the one released standalone as "Super Futebol II" in Brazil. The standalone release of "Super Futebol II" actually carries a vanilla unmodified version of World Cup Italia '90, whereas the version in "Game Box Série Esportes" carries a localized version:
Wimbledon for the Master System, earlier version from Game Box Série Esportes cartridge. This is actually a DIFFERENT ROM than the one released as "Wimbledon" in Europe. This appears to be an EARLIER build of the game, so we dubbed it [v0].
Left side [v0] from Brazil, Right side [v1] from Europe:
Coding, Music and Hacking Competitions!
The 2022 Competitions Deadline is and the end of the day. Watch this space tomorrow for entries!

BTW, I've been here for at least 23 of those 25 years :)
Mostly lurking though...

|Psycho Fox. There is a game I would love to adjust the controls on. They just feel so wrong. lol|

|I just had a quick look at Wimbledon and the players all have different portraits and names that are much closer to real-life players|

|The Psycho Fox proto also has a built-in level select which was patched out of the released game. You can patch it back in by changing the bytes at $1DC to CD B0 5E. I'm not sure if there's a way normally access the level select though|

Haven't played much but I assume it was at the least an improvement over its NES spiritual predecessor Kid Kool (how the AVGN managed to name that game's worst problems as seven deadly signs of bad design).

The developer must like the controls though because DecapAttack (Magical Hat's Turbo Flight! Adventure) controls exactly the same... :-/
Me personally, I've never had a problem with them.

Happy (belated) birthday, Omar and SMSPower!
I'm suyprised that Mr. Do's Wild Ride (#25) was ported to the MSX (the game included on the cart is an MSX port).
I like the original arcade (I knew about it thanks to emulation) but I never thought it was popular enough to deserve a conversion.

Is there some technical documentation somewhere describing how this mapper works exactly ? I don't mind reading Meka sourcecode but there are some stuff in the code below that are not very clear to me, like what exactly is a "segment" and how are they "configurable" ? or what exactly is 'technically incorrect' ?
if ((Addr & 0x6000) == 0x2000) // Configurable segment -----------------------------------------------
//RAM[0x1FFF] = Value;
// This is technically incorrect: to mimic the actual hardware
// we would either need to use an overdumped 2MB ROM, or we
// would need to preserve all the segment base bits, as page
// numbers past the end of the ROM return zeroes in real
g_machine.mapper_regs = Value;
Value = ((Value ^ 0x1F) & tsms.Pages_Mask_8k) ^ 0x1F;
Map_8k_ROM(2, Value ^ 0x1f);
Map_8k_ROM(3, Value ^ 0x1e);
Map_8k_ROM(4, Value ^ 0x1d);
Map_8k_ROM(5, Value ^ 0x1c);

|My guess is that when an invalid bank number is selected (a value representing ROM space higher than what is actually present), the emulation is simply ignoring the higher bits (to drop the result back down to a reasonable value), whereas the reality is to try unrealistic bank values as 0.|

|Tried 'Mo-eumjip 188 Hap' - and its all msx games ports. They start repeating on #53, so you get 52 different games in a single cart - and some of the best MSX1 games are in there!|
