Bandai WonderSwan Core Released

[pedroTFP]

Awesome release!
Any chance to limit integer scaling to something like 4x/5x in future releases?
Full screen image on 1080p (7.5x I guess?) is kinda blurry.

You can set custom options for resolution/scaling in the Wonderswan core in the mister.ini

[pedroTFP]

Thanks!

The vertical mode on a crt is just perfect. I didn't take it for granted.

anyone could give a pointer on where to find boot roms ? thx a lot.

Just use the update_all script.

With the BIOS updater option enabled.

After the update supporting Benesse PocketChallengeV2 I tried some roms. Did anyone find any "usable" rom as they seem to be only in Japanese?

thank you thank you !
I did have it disabled.

Man, excellent work!! Thank you for this core. Hopefully one day someone will port it to the Analogue Pocket.

Could this core be incompatible with the 4chip 128 SDRAM that Antonio Villena sells? I can get some homebrew running on the 22.04.17 version, but not always, and nothing else loads. Has anyone else have issues with the 4C SDRAM?

Most of the games I test on this core do not boot. I could only get a single game to boot, Digimon Tamers - Battle Spirit Ver. 1.5 (Japan).wsc.

All other games just sit on a white screen after I load them. I tried deleting the bios files and rerunning update all. I have tried games from different rom packs. Nothing loads.

Any thoughts on what I need to do to get more games working?

Turns out I had two cores for the wonderswan installed which was confusing me a lot. One just called Wonderswan and one called Wonderswan Color.

The wonderswan color core was probably an old build and not loading things well. I loaded the core labeled "Wonderswan" to do some testing and realized it also loaded Color games, all the games are loading just fine on the main core.

I must have tried a beta core or something and update all gave me the working core which left me confused between the two cores.

[jca]

It must have been WonderSwan Color.mgl.
This is a relatively new feature for cores emulating several devices, in this case WonderSwan B/W and WonderSwan Color.
It also created a games/WonderSwanColor directory where you can put the color games, the games/WonderSwan containing the B/W games.
I did not use this feature yet but you have to edit the mgl file to indicate which color files you have (I am not sure of the format to use).
There are other cores like this but I don't know which ones.

The WonderSwan stopped working for me too (it was fine a few weeks ago).

It boots to a grey screen (no bios detected, seemingly) and that's the extent of its current functionality.

I was aware of the newly separate folders for regular WS and WSC games, and had split the ROMs accordingly a while ago, not expecting there to be a problem (there hasn't been an issue with the similarly newly split GB/GBC libraries and their dedicated folders).

[FPGAzumSpass]

I must say that i never tried the mgl files...

In any case: both BIOS files should be in both folders. Or you just use the normal wonderswan for both color and noncolor games....

Anyone having issue with Judgement Silversword?
Even if I define the buttons, I cannot start a game.
I can use "start" to go to main menu. Then "A" and "B" don't work.
Tried other games it worked no probem.
Tried different rom version of Judgement Silversword and same result...
It was working great a few months ago so I wonder if something happen during an update..

[kathleen]

@natadiem,

Just tried this game and it works w/o any issue.

WonderSwan_23-03-03
MainMister_23-02-26
The game I used from Archive.org: Judgement Silversword - Rebirth Edition (2004-02-05)(Qute).wsc

[FPGAzumSpass]

If the game is rotated, the buttons rotate, too, so you may have to use different buttons.

Can anyone help with the correct vscale_border setting on this core? With 1:1 integer scaling it looks huge on my 4k screen.i’m using a resolution on 1080p in my Mister.ini. I’m guessing the correct number for me is around 300 or so.

I’ve tried to use a couple of settings (with what I thought was the correct maths) but when I apply an LCD post processing effect the squares are far from even - looks terrible no matter what I try.

I’ve been able to correctly set the GameBoy consoles correctly but can’t seem to do it for the WonderSwan consoles.

Thanks,

[maze]

The WonderSwan resolution is 224 x 144, the same vertical size as the GB/GBC and Game Gear, so they can all use the same vscale_border values for integer scaling. Using this formula, for 1080p they are:

Code: Select all

int.  vscale_border
 3x        324
 4x        252
 5x        180
 6x        108
 7x         36

Out of these, I find 5x is about the right size on a large screen. 4x is good too.

Of course, the above is only for horizontal WonderSwan games. For vertical games, you'll want:

Code: Select all

int.  vscale_border
 4x         92

[ShyTalk]

Thanks so much for the help!

I’ll take a look. I’m sure I used the same vscale number for the GB systems as I did with the WonderSwan but it looked way off (although maybe I just saw the vertical).

If I need a different number for vertical from the horizontal; do you need to habe the vscale entry as a particular game in the Mister.ini or is there some smart way of applying it to when the core is in vertical mode i.e.

[wonderswan vertical]
Vscale border = 324

(Obviously the above is wrong for several reasons but I can’t remember exactly how it’s set without looking at my mister.ini.

Cheers

Unfortunately I don't think there's a great solution for having separate custom horizontal and vertical vscale settings. The best I came up with is to have two lines in mister.ini, which you can manually switch between by commenting/uncommenting. For example:

Code: Select all

[WonderSwan]
vscale_border=180 ; horizontal 5x
;vscale_border=92 ; vertical 4x

This obviously won't work for games that have the player switch the screen orientation mid-game, since you need to edit mister.ini and reset each time.

I like your idea of separate mister.ini horizontal and vertical settings for each core, and/or per-game settings within a core. I would also love it if we could have our own custom vscale settings to be selectable from the user menu, similar to custom_aspect_ratio_1 and 2, so we could switch to them on the fly.

[ShyTalk]

Hmmm, well, It’ll take someone alot cleverer than me to figure it out.

What I’ve done for now is add the vertical vscale border settings to the Alt Mister.ini. I think this resets the core so any mid-game flipping messes things up.

But, in better news, your settings worked perfectly for me - cheers!

[pgimeno]

As a remainder, it's possible to have up to four different MiSTer.ini files: MiSTer.ini, MiSTer_alt_1.ini, MiSTer_alt_2.ini, MiSTer_alt_3.ini and switch between them using the same menu where you change volume.

[maze]

Yes, ShyTalk just mentioned the alternate ini files. But since changing between them resets the active core, it isn't useful when you need to change your custom vscale settings mid-game, like for games which have you rotate your WonderSwan during play.

[pgimeno]

Oh right, I should learn some reading comprehension >.< Sorry.

[ShyTalk]

No worries mate; I do that all the time

It’s a good reminder about the alt ini files, though!
