FBA WIP

[cafe-alpha]

Wonderboy on game gear (not in Monster Land, but wonderboy anyway) was one of my favorite game at that time 🙂 Thank you very much and keep up the good work 🙂

for motivation purpose :

 

[cafe-alpha]

@vbt If you're at ease with current codebase, then keep it as-is 🙂 Refactoring things generally end in time wasted and motivation killed.

Hello, what's going on over here? How's the project coming along?

Hello, what's going on over here? How's the project coming along?

i'm fixing bugs to make a release, it won't include atomic robokid and super pang won't have music.

 

[vbt]

first time with 4 layers :
1 - fg text
2 - bg1
3 - bg2
4 - bg3

it still need to find a good "hack" to select the right tiles for each layers, i can't load 1.4mb of tiles in vdp2 ram

 

[vbt]

I've burned a CD (Mediastar brand, supposed to use Taiyo yuden tech) with ImgBurn, I get some errors when it verifies the burned CD :

It also happened when I burned the august release on a Verbatim CD.

 

[vbt]

ok, thanks @fafling for the test, i can provide another version using mkisofs

EDIT : i've replaced the ISO

 

[fafling]

The new ISO is burned by Imgburn without any error.
Tested on the PAL console switched to 60 Hz with a red Pseudo Saturn v6.314 1M/4M cartridge.

As reported for the august WIP, Kronos v1.7.0 displays the same graphical problem as the console on line scrolling and screen transitions in Outrun for both SMS emulators.

Atomic robo kid displays only the status layer NBG2 on the console, the rest is black. In Kronos v1.7.0, all layers are visible.

After exiting Atomic robo kid with A+B+C+start, launching SMS (Faze) emulator freezes the console at "Loading. Please wait" message (doesn't answer to A+B+C+start). Same behavior in Kronos v1.7.0 where an invalid opcode can be seen with DebugView :

Error: Master SH2 invalid opcode
R0 = 00006148 R12 = 414B4F4C
R1 = D0036002 R13 = 80000000
R2 = 413D2162 R14 = CAAAACD1
R3 = 00000000 R15 = 00000000
R4 = 413D2162 SR = 00000100
R5 = AAAAAAAB GBR = 00000000
R6 = 41E00000 VBR = 06000000
R7 = 00000000 MACH = 00000000
R8 = 413D2162 MACL = 00000000
R9 = AAAAAAAB PR = 00006156
R10 = 06010A24 PC = 000067B4

fixed, new iso uploaded thanks for these tests 🙂

There's no longer the invalid opcode when launching Atomic robo kid then SMS (Faze), but there is a new one when launching SMS (CZ80) then Atomic robo kid (freezes emulation in Kronos v1.7.0 during initialization of ARK) :

Error: Master SH2 invalid opcode
R0 = 00000104 R12 = 00000000
R1 = 06021028 R13 = FFFFFFFF
R2 = FFF0FFF0 R14 = 002FC83C

fixed but not yet published

With the last version, there's no longer invalid opcodes, but if I launch SMS (CZ80) then Atomic robo kid, some sprites stay on screen in Kronos v1.7.0. It doesn't happen with SMS (Faze) launched before ARK.
Here, I'm not shooting and some lasers stay on screen, moving with the character (laser drawing commands are visible in VDP1 debug window) :

The first incorrect sprites appear during ARK ROM check.

oops, i had removed a cleanSprites at driver init :/

 

[cafe-alpha]

This happens a lot here too : the few weeks before (and after !) a release are privileged moments to find enormous bugs 😀
Good luck in finalizing this release !
