Too bad this is as far as it gets.

Too bad this is as far as it gets.

Not so bad...I'm sure you will be able to make it work !

I was poking around and noticed that there's a partial dump of Espgaluda (just the 68k program rom and some pal dumps) floating around ^^

So I took some time and decrypted it (though I can't verify whether it's 100% or not...)

Quite a lot of text and information there. ^^

Hello all,
I have just one little question, kov2p not work in new mame 0.132? I want to know if it work on this or no?
Thanks for response

[iq_132]

I imagine it will work just fine using the code here:

http://neo-source.com/index.php?topic=1170.0

[Multipass]

Hmmm, i had tested it, but not work, maybe is a bug in mame plus 132 release?

I was poking around and noticed that there's a partial dump of Espgaluda (just the 68k program rom and some pal dumps) floating around ^^

According to Guru, this has been dumped, it's struck through on his list. Ketsui too.

[iq_132]

I read somewhere that some of these that were dumped are the expensive, rare versions and are easily programmable into old, non-rare versions.  That's one of the reasons these aren't released.  Not only that, I'm sure the internal ARM7 roms aren't dumped for these, so even if they are released, the odds of them being in working order are very small.

there is not much scerets left on IGS027A...
it is easy to get most of them (games before theglad?) dumped via trojan
but the newer chips(theglad/svg/killbldp...) use an eXecutable Only Memory region at the start, ~0x200 bytes, varying from game to game. Even for these game we can get the internal rom dumped and patch it to get game boot and play, not so  hard ...
(I dont have idea about those CAVE game as I dont have PCBs)

I'll certainly be waiting for Killing Blade Plus' internal arm7 rom to be patched and it to be playable then.

[Xenepp]

Shame about the Cave games. They are some of the most under rated games out there IMO.

[xingxing]

it is patched already, otherwise you cant see the TITLE ...
but the internal rom is a BADDUMP
it was dumped some years ago and i dont know any good way to verify it at that time.

Bee Storm - DoDonPachi II (V101, Korea)

seems to ba a valid dump...

Code: [Select]

v101_16m.u8 crc 5e5786fd size 2097152

[CaptainCPS]

Wow! Thats nice I been wanting to play Do Donpachi 2 for a long time! 

SeeYaa!
 

[SuperPang]

Works without problems? The bullet processor works without the ARM7?
