Keep up the good work! :)

Lets see if I understand well then each game need some tricks on the protection in order to work under makaron?

No, each game needs it's protection understood and correctly emulated :)
OMG makes only basic checks so a simple data patch will make it work. Other titles might require real-time data substitution.

Ok now I understand and thanks for your answer :). So you will have to deal with each game protection, that isn´t funny I guess :p.

Hi
Hope this is the right place to raise this issue.
I am having a problem with Makron for both Naomi and the Dreamcast,
whereby when I run the emulator, all I get is a black screen, which some times flickers the DC logo very quiickly, but then goes black again.
I made sure that all the setup is done correctly (and bios files correct and in the right place), and have spent quite some time trying to troubleshoot this problem, but without success.
I have attached the output from the emulator :-

Can anyone (thanks DK) give any good ideas or answer to the reason I get a black screen when running the emulator.

Thanks All

i can`t remember why, i`m using 0.84.11.0 version on naomi. I think was most recently versions don't running nothing for me. But still can't run any game in dreamcast makaron.

Test 11? Try a bit newer version.
BTW what CPU is this, Athlon XP?

The CPU is a Sempron 2800+ (rebadged Athlon XP, i think).

I've tried all current Makron version, ie, T11, T11.1, T11.2, unless there are later versions i've missed/unre-leased (?!!).

Its a strange problem, as when I run makron (DC or Namoni), I get a black screen, but I see the DC logo flash very quickly a couple of times. So its trying to run it but hits a snag somewhere.

Do you have any inspiration ideas/opinion/suggesstions/things to try,etc?

Would love to play/use this excellent emulator, so I hope we'll eventually get to the problem.

thanks
Nigel

Hi DK
Ran this again with T11/2 agnd got this error diagnostic :-

Note the DIRECT3D error. Any help advice on this issue.
Thanks.

Great, hurray for you, mr. makaron!

But what i'm reading? "Protection on this particular cart is rather easy to defeat" jajaja nice this. i'm starting to think that you're mr. kickass.

I have a question. a protection on a game is something like a encrypted data? if you think that is hard to explain this, forget it ;)

saludos

Depends. Some games could use encryption, but this one does not. Instead it expects some data to appear that is not in the ROM, rather procedurally generated by the cart hardware. In other words, just dumping the EPROM and mask ROMs is not enough to get it running properly.

ummm Marvel vs. Capcom 2 is a similar rom cart as Quiz Ah Megamisama, you think you can also break the protection

thanks

Is there a function in Makaron to remove the jagged edges in the graphics? I think it's known as anti aliasing? the emulation is flawless for me (Jet Set Radio) but it can look a little sharp sometimes and it would be nice if I could soften it up.

Thanks.
