I cannot find the Athletic Land ROM with the CRC-32 indicated in the Readme.txt. I tried TOSEC, No-Intro, msxarchive, etc. Is it a custom modified/patched version?

The same problem with the Megalopolis SOS and Time Pilot roms. In this case the dumps with the specified CRC in the read-me.txt don't even exist in the openMSX database.

I have all the roms below, which are registered in the openMSX database (latest version: softwaredb-20190718-203820.zip)

According to the database I'm missing only "Athletic Land (c0476fab5ca3c69b381bb8c43efea1277d7a1b43) ([RC-700])", maybe this is the one with the required CRC?

But in the case of Megalopolis SOS and Time Pilot, and according to the openMSX database, I'm only missing your GDX SCC versions.

Hi GDX, Thanks for the time spent with this incredible MSX games set. I'm in the process patching every games in the IPS list.
the game Cabbage Patch Kids the SCC is just used for BGM comparing it to Athletic Land the SCC is used for BGM & SFX so my question is the applied patch for Cabbage Patch Kids just enhanced little bit the Audio Experience comparing to Athletic Land that is right?

@Diedel: I have applied for Athletic Land the CRC used was 7B1ACDEA from Athletic Land (J) and it seem to run fine.

For Fix Dig Dug 32KB(CRC 3C749758) to 16KB(60311bde) you'll need to apply this patch:

https://www.msx.org/downloads/patch-rom-size-for-dig-dug

PS: I'm very impressed with the improvement in the Audio Quality with GALAGA just the missing Big Explosion when you die but in overall is great. That make think about if I could add that using a Music Module ADPCM Engine what do you thing guys?

You can use the version 7B1ACDEA of Athletic Land, it's is same as the 9C4A8983. Unused data between 3F40h and 3FFFh are all 0FFh.

Time Pilot (85DBC74B) is the version with Konami's logo that starts on a blue background (instead of black). (SHA1: ce45e159d52fd4dee7f508be9d08a7c719ff9839)

About Megalopolis SOS I think you can also use the version CF744D2E. Otherwise replace the string "00 00 21 00 E0 36 00 11 01 E0 01 FF 1F" with "80 F3 21 00 E0 11 01 E0 01 FF 0F 36 00" at 011Eh from the version with an hexa editor to get the 8C3C891A.

Hey, GDX could you please check King & Balloon IPS because I can't get SCC sound from it. I have test it with OpenMSX and MFRSCC/Snatcher Konami Sound Cartridge 128K

- with NMS8245 + Konami Sound Cartridge 128K + ROMLOAD always get FREEZED in Main Title
- With Philips VG 8020 + MFRSCC the game RUN but Not SCC Music or SFX is output just the PSG is OUTPUT like nothing was modded.

Thanks in advance.

Thank you Alexito. I was wrong with checksum. You must use the 16kB Rom with the crc32=1EEBA987.

at last I have converted all the 22 games to SCC and the experience was really interesting I see potential in some games for enhancing with ADPCM Samples like Galaga, Bosconian,Rally X, Pacman, Tank Battalion, Time Pilot.
Will see what happen in the next days.

Thanks GDX.
