Cadillacs and Dinosaurs Turbo (bootleg set 2 (with PIC16c57), 930201 etc) [Bootleg, No sound] AKA dinopic4.zip ?

[drtanzil]

No, not dinopic4.zip.
For FBA NEO its- dinotpic.zip
For EKMAME its dinohb.zip

Im sharing a FBA map for dinotpic -

The rom runs 100% on EKMAME emulator with all hacks (There its called dinohb.zip)
I have a snippet of dinohb -
Got from:
https://neo-source.com/index.php?topic=564.msg4835#msg4835

for dinohb- sound = OK, Graphics = OK,
Player change using Start Button = OK.

P.S- This rom is widely popular on asia as Arcade machines there played this ROM.

@crystalct : Is it the right place to notify this issue?

[crystalct]

Yes and no.... the sources to be modified are those on the github libretro fbneo core... once the problem has been solved (big endian issue) on the original sources I could recompile them for PS3. You should open the issue there.

[drtanzil]

@crystalct : I have downloaded FBNeo from git & compiled it on my PC today. There is no audio & GFX (Black sky) issue on there for dinotpic ROM. Requesting you to compile with latest FBneo core.

[crystalct]

A PC has a little endian CPU. PS3 has a BIG endian CPU. It's a Big Endian Issue.

[drtanzil]

I see. But there might be a fix.
This rom also runs on Android device which is big endian cpu (not sure) using fba4droid emulator. Sound, GFX & hack all works okay. Fba4droid is not open sourced, dont know how they solved this.

[drtanzil]

Thanks @crystalct . I posted and got reply from barbudreadmon:
Big-endian (ps3) compatibility should be fixed with 728246d

[crystalct]

Android ARM is not Big Endian CPU

[drtanzil]

Thanks @crystalct.
As per your advice i posted on FbNeo git
They have updated d_cps1.cpp on their git with big-endian fix.
They said-

Big-endian (ps3) compatibility should be fixed with 728246d

here is my orginal post

Now how to get it fixed on PS3 ?

Im sharing my PS3 Black Sky Issue for dinotpic

[barbudreadmon]

@crystalct oh, i thought you weren't active anymore, we didn't get a reply the last few times we tried to ping you about big-endian issues

[drtanzil]

Great to see @crystalct and @barbudreadmon together on the post!
I was relaying one's request to another, acting as a realy, ha ha!

[crystalct]

Sorry, but my free time is almost zero... :-P

[drtanzil]

@crystalct @barbudreadmon Both of you have done a great work! Spending lots of time & effort to keep alive the nostalgia of Arcade era. Requesting to keep up the good work and also requesting to recompile the original core for PS3.

[crystalct]

I should have completely updated the FBneo sources, but the last time I tried to do so, the compiled core had become so large that the PS3's limited RAM became insufficient. I just added changes from 728246d, but it wasn't enough, there must be more or I have to do a complete update for the light version of the FBneo core for the PS3
