Loading LD software Lascommate “Junior high school mathematics” gives following Japanese screen and then stops…


I’m using a PX-V60 computer and LD700 LD player. LD Box is mentioning PX-V7 and LD-V500. From what I understood PX-V60 is similar to PX-V7 except for RAM memory size. E.g. Interstellar and Starfighter work well with my set-up.
What's the problem?

It's talking about "ROM Cartridge" and "set" (that's all katakana I found).

Anyway, cool that you bought these ultra rare LD's! Could you make some nice detailed hires photos for me to add to the Generation MSX database?

Ah, indeed, the two kanji in front of ROM mean "kanji" Smile

Manuel: Hi res. pictures sent.

So I need a Kanji ROM to run this LD? Anybody with more info?

Some screen shots (sometimes it is a strange setting for a mathematic course......)

Yes, you do need a kanji rom.
I have no idea whether any random kanji rom will do; probably your safest bet will be the kanji rom supplied with the Lascom software, but it might be pretty hard to find...
All I have is a picture, so that you know what you should be looking for.Tongue

I've made a dump of the first laserdisc, and a BASIC program is loaded on startup. Nearly the first thing it does is:

130 A$="":A=&Hd8:OUT A,0:OUT A+1,0
150 IF A$<>"PNR" THEN (seek to rom is not present & hang)

Does anyone know this ROM?
