DU: It's like even rom dumps are still living in 1945

Blackfish sent us a dump of his Strikers 1945 board which is, I think, a previously undumped World region unprotected set.
Arzeno Fabrice and rtw dumped a bootleg cart of Powerstone 2.
Porchy dumped a bootleg of Frogger.
Hammy dumped an alt version of Hidden Catch running on the 3.02 hardware.
Kevin Eshbach documented Iron Stewart's Offroad Racing.
If you want to help us buy more boards:

That Frogger board from Porchy looks eerily similar to the boards used in Take Off and Explorer, but with no Sidam code. Font also matches. Is the crystal on there 12 MHz?

> Yep
Sure definitely seems like it was made by the people who made Take Off and Explorer. No other Galaxian derivative I've seen tries to do everything through a crystal at a much lower value.
I'm now wondering if it does backgrounds as seen in actual Frogger boards, or if the backgrounds are entirely blue or black. If Porchy could also measure clock inputs for the two Z80 chips/provide a reference video if he got the board working, that would be nice.

Oh, and regards to Explorer, we're missing a reference video as well to determine if a starfield exists. It, Take Off and presumably this board also expect a different sound timer, or else the tempo is way too fast assuming the sound CPU clock is 12 / 8 MHz, not sure how it works there either.

not surprising, it's the cheapest type of thing to bootleg, so biggest margins, largest established user base, easiest to make look genuine unless you open them up.
i'm surprised we haven't seen *more* of these things, although I think maybe we have and people confuse them for prototypes.

At least 2 Chinese companies manufactured Sega carts (Atomiswave, which is similar to Naomi) :
Xing Le and San Star LTD.
I don't know if they are considered to be bootlegs or unlicensed copies ?!
What's the difference between bootleg and original cart ? Are they exact the same copies (hardware vise) of original carts or the only diff. is licensing (they break the copyright law) ?

depends
for this one they replace the protection chip with an FPGA and instead of real time decryption they fetch pre-decrypted data from a previously unused area of the ROM (but otherwise don't modify the game code)
for the Atomiswave bootlegs apparently most of them were made from a faulty copy of the game (or earlier faulty bootleg) so there are corrupt backgrounds and frames of animation in a lot of them.
some of the NeoGeo ones have weird access timing causing even more glitches and slowdowns than the system already had (also with Garou the majority are based off a hacked version of the prototype as there's no final version without encryption and custom banking)
in other cases the bootlegs are unauthorized extra cartridges produced at exactly the same time as the originals to the same standards.
there's no single answer to your question.

no, they are not. AW bootlegs roms contents match original carts.
glitches in some games caused by incomplete/incorrect protection CPLD "ping-pong" protocol simulation.

hmm I was told differently by people dumping them many years ago, saying they repaired some by reflashing the MAME dumps onto them, but ok.

probably we are talking about different games and glitches. I was about Samurai Shodown VI game.
but yes, I think you was right, I recall something about bad data in other games.
