Topic: NeoRAGEx decrypted-roms drivers for FB Alpha.... help needed!

[mai]

still having problems with some old dumps, such as aof3 (similar to official MAME-set, except c1-c6 roms):

Code: [Select]

{ "096-c1.bin",   0x400000, 0xf6c74731, 3 | BRF_GRA }, //  3 Sprite data
{ "096-c2.bin",   0x400000, 0xf587f149, 3 | BRF_GRA }, //  4
{ "096-c3.bin",   0x400000, 0x7749f5e6, 3 | BRF_GRA }, //  5
{ "096-c4.bin",   0x400000, 0xcbd58369, 3 | BRF_GRA }, //  6
{ "096-c5.bin",   0x400000, 0x1718bdcd, 3 | BRF_GRA }, //  7
{ "096-c6.bin",   0x400000, 0x4fca967f, 3 | BRF_GRA }, //  8
background is ok, but sprites look like a mess...

in older MAME source said:

Code: [Select]

ROM_LOAD16_BYTE( "096-c1.bin", 0x0400000, 0x200000, 0xf6c74731 ) /* Plane 0,1 */
ROM_CONTINUE(        0x0000000, 0x200000 )
ROM_LOAD16_BYTE( "096-c2.bin", 0x0400001, 0x200000, 0xf587f149 ) /* Plane 2,3 */
ROM_CONTINUE(        0x0000001, 0x200000 )
ROM_LOAD16_BYTE( "096-c3.bin", 0x0c00000, 0x200000, 0x7749f5e6 ) /* Plane 0,1 */
ROM_CONTINUE(        0x0800000, 0x200000 )
ROM_LOAD16_BYTE( "096-c4.bin", 0x0c00001, 0x200000, 0xcbd58369 ) /* Plane 2,3 */
ROM_CONTINUE(        0x0800001, 0x200000 )
ROM_LOAD16_BYTE( "096-c5.bin", 0x1400000, 0x200000, 0x1718bdcd ) /* Plane 0,1 */
ROM_CONTINUE(        0x1000000, 0x200000 )
ROM_LOAD16_BYTE( "096-c6.bin", 0x1400001, 0x200000, 0x4fca967f ) /* Plane 2,3 */
ROM_CONTINUE(        0x1000001, 0x200000 )
is there any FBA analog of MAME ROM_CONTINUE()? or some extra code needed?

thanks for your attention and patience

Try HARDWARE_SNK_SWAPC  It may work.

I've already tried, not working... thanks anyway...

but when I've put this code in (just an experiment)...
some progress appears (you may see differences from original code above):

Code: [Select]

{ "096-c1.bin",   0x200000, 0xf6c74731, 3 | BRF_GRA }, //  3 Sprite data
{ "096-c1.bin",   0x200000, 0x00000000, 3 | BRF_GRA }, //  3 Sprite data
{ "096-c2.bin",   0x200000, 0xf587f149, 3 | BRF_GRA }, //  4
{ "096-c2.bin",   0x200000, 0x00000000, 3 | BRF_GRA }, //  4
{ "096-c3.bin",   0x200000, 0x7749f5e6, 3 | BRF_GRA }, //  5
{ "096-c3.bin",   0x200000, 0x00000000, 3 | BRF_GRA }, //  5
{ "096-c4.bin",   0x200000, 0xcbd58369, 3 | BRF_GRA }, //  6
{ "096-c4.bin",   0x200000, 0x00000000, 3 | BRF_GRA }, //  6
{ "096-c5.bin",   0x200000, 0x1718bdcd, 3 | BRF_GRA }, //  7
{ "096-c5.bin",   0x200000, 0x00000000, 3 | BRF_GRA }, //  7
{ "096-c6.bin",   0x200000, 0x4fca967f, 3 | BRF_GRA }, //  8
{ "096-c6.bin",   0x200000, 0x00000000, 3 | BRF_GRA }, //  8
now sprites looks very strange (suppose something wrong with transparent masks and some gfx glitches still remains), however it don't look like a mess no longer, I can see figures and animation...

but I don't clearly understand, what I've done and what I should do with these c1-c6 roms...

Hi,

if you check an old Nebula dat, you see that C1 through C6 need to be byteswapped (not C7/C8)

thanks IQ, you're great!
