Game patch for Zanac EX

MRC user Victor strikes again. After the famous patch for Usas, the Salamander smooth scroll patch, and the Nemesis 3 patch, here is his latest master piece: A game patch for Zanac EX!

These are the improvements:

FM music arranged by Mstz80ax who composed the full soundtrack specifically for this patch. A superb job!
TurboFIX
Some options at launch: infinite lives, PSG original sound, double PSG sound with supportive cartridges
Some routines have been optimized (faster than original game)
Everything in the same ROM size: 128 kbytes

Imagine the thrilling soundtrack from Zanac EX with MSX Music and two PSG support. This makes this addictive game much more infectious! Have fun with Zanac EX. Once again.

This patch only works on MSX2 computers or higher.

I tried a few loaders and the game doesn't work (but works if installed in ROM): It either freezes on the bumper screen (with the "press ..." blinking) or gives a white screen.

Have the same problem here. Could also be related to the fact the when loaded in RAM the "AB" header is removed ? (the problem also happens when flashing on a flash device with SofaRun, that also removes this header).

Launching the game in RAM is interesting on turboR (using the internal mapper), as this gives the best performance. Must say the game is also indeed harder in turbo mode !

Por Louthrax

Prophet (2051)

05-01-2019, 11:04

Made some more tests this morning:

The problem is not related to "AB" header.
Games works fine with SofaROM on devices requiring no ROM patching (MFR, Carnivore, GR8Net, Multi-MSXRAM), if you use the "No disk driver" option (/X). The disk driver is enabled by default by SofaROM, is option frees some RAM.

The game works with EXECROM and a Megaram! But without FM music
Load the ROM with the /R5 option and then force PSG sound (keep "P" pressed).
It seems that OPL detection doesn't work correctly, as it always says "OPLL(MSX-Music) found!!", even if the device is not present, and then freezes.

@"What's the problem ? No sound in the other PSG, or it doesn't boot??"

Well, the PSG sound fine on NMS8280 at 3.5Mhz but I want to try the Extra PSG on GR8NET at 7mhz because this Computer have 7mhz Switch and at 7Mhz everything look and sound better inclusive other games at 7mhz BGM sound good check this link about XENON enhanced at 7Mhz where the BGM is on the Extra PSG.

I did but still I don't get the Extra PSG on GR8NET activated just the internal PSG is working I can assure that because the External Audio Output for EPSG,YM2413,Y8950,PCM On GR8NET is Connected to my RIGHT Speaker and NMS8280 Audio Output (PSG) on LEFT Speaker.

But, do you hear the sound FXs?? Those must be heard in the second PSG (ports 10h & 11h)

Sorry, but if you don't hear any FX is because the routine works correctly... That's a GR8NET problem... are you sure you have activated the second PSG in the GR8NET??

Por alexito

07-01-2019, 23:53

Yes is activated all the time when you TURN ON or RESET the MSX. GR8NET offer to SAVE the Setting and the INFO SCREEN at booting confirm that. Like I told you before the same GR8NET cartridge was tested with other MSX2 Computer and all the features works flawless.

and yes just the SFX on Internal MSX NMS8280 (PSG) is working fine seems like the changed 0xC8 doesn't affect nothing on NMS8280. Do you have a more radical approach to force the Extra PSG get activated ?

I have patched Zanac Ex with the Double PSG Forced but for our bad luck NO Extra PSG through GR8NET Audio Output yet with my lovely NMS8280. You can Test this version also via OpenMSX --> My Setup was NMS-8245 and MegaFlash ROM SCC plus.

Thanks Victor for all your effort.

~~Let me do something interesting by my part just replacing the IO ports 0xA0 and 0xA1 to 0x10 and 0x11 and will see what happen.~~

On Zanac Ex with Patch Ver 1.02 and OpenMSX when The Main Game Title show up push BREAK button on Debugger and change 3 offsets in Z80 RAM:

0XE1EF 10
0XE1F4 11
0xE1F8 10

and you can hear on OpenMSX with Mega Flash ROM SCC Plus the BGM on the Main Title executing very well using just the Extra PSG on MFRSCC+

so I did a quick patch to this ROM just changing 3 offsets:

0x1BC6F 10
0X1BC74 11
0X1BC78 10

and the Extra PSG on GR8NET now it replace the internal PSG (NMS8280) but it is not what I want to hear I want to hear both PSG Audio Chips so I can feel the improvement. Sorry for be too demanding.

PS: I start thinking the problem is NOT the Keyboard Layout.

I have modified 2 offsets only after applying patch Ver 1.02 and we get SFX output on GR8NET (ExtraPSG):

0x1BB37 10
0x1BB3C 11

switching at 7mhz on NMS8280 the SFX via GR8NET sound pretty good but Internal PSG sound little high pitch but not bad after all.

PS: Definitely no problem with the KEYBOARD Layout (NMS8280) because I have tested "I" key and I got Infinite LIVES.

Hey Victor, nice work!

I am adding a "Double PSG" Extension to WebMSX so it can play this version to the full!
It already has the 2 PSGs working OK with the "D" forced mode.
But if fails to enable the 2 PSGs by default since the check for the MegaFlash SD fails.

WebMSX does not yet support the MegaFlash SD (and there is no plans to fully support it, since it already has Nextor support and FlashROMs are not really needed in emulators).

I read somewhere that the 2nd PSG is undetectable by itself, so this is probably the gotcha here.

So I ask you: can you please explain the check that is performed to detect the 2nd PSG? Does it NEED to check for the MegaFlash, or could it check in any "more generic" way?

Maybe I can emulate just the part that gets checked so we can activate the double PSG by default.

Thank you!

The main problem is that in almost all devices, only the writable PSG channels are in the other PSG (ports 10h and 11h), so you can't check it directly...

I just check for the MegaflashROM SD firmware.. that's all

It's easy to detect, for example, the GR8NET, but in this device you can disable the double PSG (in config)... so it's not good to force it... The same with FLASHJACKS device...

I'm a bit confused with the double-PSG thing. Is it really necessary for the OPLL soundtrack?

I mean, I originally thought that it was meant to be used to play the SFX, only for the PSG soundtrack, since the original game steals music channels to play the SFX and the music ends up being played on a single PSG channel most of the time.

But for the OPLL soundtrack, I thought that this would be unnecessary, as there are plenty of channels available, and Mstz80ax's in-game soundtrack seems to use only the PSG channel-1 for complementary drumkit sounds, leaving its channels 2 and 3 free for the sfx.

And, of the game sound effects, only two of them use the channel 1 (sfx 0Bh and 1Ch), but:

- 0Bh was remade as "WARP.MGS" in the OPLL soundtrack.
- 1Ch was remade as "BOSSDEST.MGS" in the OPLL soundtrack.

So, is the double-PSG feature really necessary when the OPLL soundtrack is played, or is this feature only necessary for the PSG soundtrack? If that's the case maybe it could be made a bit more clear in the README?

I thought the same when I started with this project.. but when PSG SFX write in PSG register 6, then the PSG sound is channel 1 (for music in OPLL) is corrupted.

I see...
Maybe you could try to detect the PSG from reading its ports first, and if that is undetectable, then try to find the specific devices?

I think it would be a good approach, and also much more future-proof, since it would correctly detect any extra PSG that is already readable now, and also any new hardware that may have it in the future!

Would that be possible/not too difficult?

GR8NET PSG is not configured on port 10H by default I think. It shows on the boot screen, if it says A0 then you need to use CALL NETSETPSG(3) and then CALL NETSETPSG. See GR8NET manual §8.4. (Not sure why it’s not just immediately reconfigured and you need to call it a second time without argument.)
