Problems with custom generated modelines
makya:
Theoretically you could use the exact modeline that you get in arcadeOSD but I believe it's still broken.
What I did instead is translating the modeline I want into a narrow crt_range.

Can we make forced use of the 248p one somehow ?

Hi, even though you can do it, it doesn't make sense.
A) If the game is 240p, you lost pixel perfect
B) Your screen shows 240 vertical lines at 60hz, if not, it is configured wrong and you must set vsize with pots/service menu
C) Vertical games with 256 lines can be cropped to 240 lines for horizontal monitor with same original freq; otherwise groovymame go down frequency

Yeah, I limited the upper hertz range a bit and got it to do modes that donīt go out of sync. Thank you :)

Yeah, the problem is I donīt have an original remote for this TV :( and I donīt see any potentiometers in the chassi nor referenced in the service manual...
I donīt get what you say in point C) though... // EDIT: Ah, I kinda get it now... but yeah, no, I want this for any game, even horizontal ones. The thing is some games are still OK because they were designed with overscan in mind, that is, markers, numbers, etc. are enclosed in a closer rectangle... but otherīs are not...
Thank you.

Here's how to access service menu. Should be feasible with a universal remote.

OMG OMG OMG, Thank you so much !!! I had a look in the manual some days ago but I thought a clone/universal remote wasn't going to help :O but you are right, the buttons referenced are normal buttons !
Thank you, ordered a compatible remote, I'll report back when it arrives and tey this :)
