Hi, where can I download the most current core? Thank you

In his Github repo:

https://github.com/MiSTer-devel/MSX1_Mi ... 2/releases

NinjaWarrior

Thank you for sharing, I have not played it but I will give it a try this weekend

NinjaWarrior

A lot of the reason you have all this great stuff to play with is the GPL. The vast majority of the software on the Mister exists because it can build on all the GPLed software that came before it, like the Linux kernel and all the userspace utilities. It's not "legal gibberish", it's important . Trying to stick proprietary code into a G...

NinjaWarrior

Sooo, in short... someone ports a great core, another one comes with legal gibberish and we are f**** up. Great, I despise this nonsense. But, hey man, we are adults so keep it legal baby.

Regarding the core, great work @rampa. Don't let this discourage you for future developments.

P.S. This thread smells like teen spirit

NinjaWarrior

A CPC Plus core will boost new developments for sure, I hope it can be doable in near future crosses fingers

NinjaWarrior

Finally this WONDERFUL core is in the Official Repo! Congrats for such a fine piece of art you have made! I am enjoying it every time I can.

NinjaWarrior

Even within the same model you can get different colours due to tolerance of components. Totally true, and most MSX 1 computers are now almost 40 years old, so we can expect some variations in colors or signal output quality. Overall, I think the MSX 1 palette is fairly accurate and we talked about it in a Retrocrypta Twitch live (in which @moleku...

NinjaWarrior

I checked the colors with a real MSX 1 (SVI-728) and Molekula MSX core seems very accurate on my setup using The Maze of Galious cartridge. The gradient is not present on real MSX, purple is very accurate, so the differences pointed out seems like an emulator artifact to me. I took some photos only realizing that phone camera changed colors and the...

NinjaWarrior

Is this core ready to be in main? I think it works really good, if you need some testing @molekula please ask, we can provide some feedback to help the debugging/implementation.

New version 20220117 adds support for Konami mappers, Konami SCC, ASCII8, ASCII16. If ROM > 1Mbit (128 kB) is loaded, used SDRAM in the core. If SDRAM is not available the ROM will not work and BASIC will appear.

That is just AWESOME! Thank you!

NinjaWarrior

Glad you had it working! I don't know how can you handle multi-load cassettes and saving on OCM / Sofarun, if it is even possible.

Good luck! I hope Emu68 dev joins in!

NinjaWarrior

It worked... something worked. I changed several settings and now I am getting this benchmark with more than 50k dhrystones. For some reason the Chip speed at the bottom now only says 1.06, but MFlops is also a bit higher. Also its now 52.48 Mips instead of 47. You can check my captures in the previous page, I get 54 mips and 52k dhrystones withou...

NinjaWarrior

Seems D-Cache impacts chipmem speed, and you need to add some quite amount of Fast RAM to boost the MIPS. I am testing now real scenarios to check if it really translates to real use.

NinjaWarrior

Good question. Might be the version of SysInfo I am using? Pretty sure I have noticed different scores betweendifferent versions. I just tried running that dhrystone_amiga tool and it gave me 135135 dhrystones/sec after running for 5... whatever 5 of the l option is. It also gave a score of 76 dmips. I will try other versions of SysInfo. My settin...

How did you manage to get so many MIPS? I just boot the sysinfo disk (without HD - 68ARM (qemu) - OCS - 2Mb fast) and I get 10.52 mips... If I use musashi I get even less.

NinjaWarrior

I know that this core is for saving the actual machine, so I think that it will not support Japanese. Therefore, I hope that the completion of this core will create another core of the actual Japanese machine. As an option, it would be nice to have a fast tape load. Would be nice indeed to have a proper core of a japanese MSX machine, let's hope t...

NinjaWarrior

I hope that this core can use Japanese BIOS and support high-speed loading. Not likely to happen, as the original machine implemented (Philips VG-8020) does not have these features. Or, I'd like to know how to do the above operation using SofaRun on the standard core. I checked your VHD file and game, and first, the SofaRun version is old (3.2), t...

NinjaWarrior

Tested and working! I tried some games (like Frontier) and demos, obviously some glitches and problems, but looks VERY promising!

NinjaWarrior

Thank you for the information! Immediately I tried it. I like this core because it is very easy to operate. The game has started! But there is a problem. Wingman is a Japanese game, but it has garbled characters. It may be useless if it is not a Japanese BIOS. Since this core really reproduces the actual machine, the loading of the cassette is as ...

NinjaWarrior

'Invalid module format' is the problem, which kernel do you have? I have this and built them against it: Linux MiSTer 5.14.5-MiSTer #2 SMP Fri Sep 17 03:26:30 CST 2021 armv7l GNU/Linux Oh crap that reminds me, I think Sorgelig did a 2nd kernel update. I need to update my mister and rebuild these. Thank you for your reply, I figured that but I was ...

http://www.64kib.com/mister_hybrid_files/MinimigHybrid_20220113.tar.zst Thank you!! I tried it but I only get a black screen if I activate the 68arm option, working as usual if I leave it at 68000. Copied archive files to media/fat. This is what I get if I try to launch the script "start" from ssh: media/fat/Minimig_Hybrid# start pid 144...

NinjaWarrior

You can use the new MSX 1 core:

viewtopic.php?p=41471

https://github.com/tdlabac/MSX1_MiSTer

which is nestor.sys/sofarun free and includes cassette and rom loader directly using OSD.

NinjaWarrior

I simply downloaded the file and copied it to the _computers directory. It's working but slower all games I've tested and before it was at normal speed, the sound is now perfect. Maybe you are running it at 50hz, as it should be. As you are used to a Brazilian MSX (60Hz) that's may be the reason you are seeing it slower (if your Mister display con...

Here is working ok, and this evening we tested it in a Retrocrypta live in Twitch, maybe your config got corrupted?

Look Github. Release 20220110

Thank you!!! I will test it tonight more thoroughly but Knightmare sounds good, now we have joystick, more bram... fantastic!

NinjaWarrior

got it, thank you! I was really desiring to try these games and only rom option was available :lol: No worries :mrgreen: , there are lot of repositories who offer CAS file format, I think the one you linked had also CAS files where you can download Robocop and Batman The Movie to check them. If by chance you try Robocop, please check if it shows g...

NinjaWarrior

Friend "molekula" is it possible to switch from rom to the famous Brazilian rom from MSX Expert 1.1 Gradiente? follow the link below: https://www.msxpro.com/hardware/roms/expert11.zip Molekula is implementing a VG-8020 machine, which has a different slot mapping than Gradiente Expert GPC-1, and also the VDP is different, as the VG-8020 u...

NinjaWarrior

I tried Robocop and Batman the movie roms and it only reboots. It might be an issue with memory? This may be due to lack of mapping support from cartrige. Currently no external mapper is implemented. More information could be provided if I know which specific ROM it is. These games were originally released in cassette format. Jordi is trying to lo...

NinjaWarrior

Does the core support audio in (loading from tape?) Yes, today's version allows emulation of the audio IN and cassette player. However, I have not tried the audio IN. I don't have it available on my HW. The cassette player emulation assumes a CAS file for MSX from the Mame project. I have tested it cursorily on one game composed of several files (...
