schermo

[bang]

salve ragazzi e siccome vedo che siete preparatissimi vi pongo un problema.
Ho un vecchio gioco portatile...vi ricordate il game gear.
Siccome di quei giochi non si trovano,non lo uso piu' e c'è l'ho buttato...prima di venderlo volevo sapere se posso utilizzarlo come uscita.
Cioe' ho la schedina per vedere la tv..m io ci volevo attaccareil lettore dvd...siccome non ci sono entrate volevo sapere se riesco a collegare i file dell'uscita dvd.
Possibile?
grazie

ho trovato la mia rispopsta da solo e cioe' l ascheda tv turnetr possiede un jack dove inserire uno spinotto per far entrare video e audio...ora pero' il mio cervello pazzo ha pensato perchè non smontare il video della console per utilizzarlo.
Bene a smontarlo non ci metterei niente ma come far accendere e utilizzare lo schermo?
dopo varie ricerche ecco quì trovato alcuni dati:
Display modes
----------------------------------------------------------------------------
The TMS9918 has three bits which select different display modes called M1,
M2, and M3. However, only four combinations of these bits are documented
in the TMS9918 manual:
Mode 0 - Graphics I
Mode 1 - Text
Mode 2 - Graphics II
Mode 3 - Multicolor
The other four undocumented modes are simply variations of the above, they
are not unique.
The SMS VDP added another mode select bit that enabled mode 4, which is
specific to the SMS. The SMS 2 and GG VDP changed the function of the
TMS9918 mode select bits to pick different resolutions for a standard mode
4 screen. The Genesis VDP added mode 5, which is specific to the Genesis.
Here's a list of all possible display modes:
M4 M3 M2 M1 SMS VDP SMS 2 / GG VDP
-- -- -- -- ---------- -------------------------
0 0 0 0 Graphic I Graphic I
0 0 0 1 Text Text
0 0 1 0 Graphic 2 Graphic 2
0 0 1 1 Mode 1+2 Mode 1+2
0 1 0 0 Multicolor Multicolor
0 1 0 1 Mode 1+3 Mode 1+3
0 1 1 0 Mode 2+3 Mode 2+3
0 1 1 1 Mode 1+2+3 Mode 1+2+3
1 0 0 0 Mode 4 Mode 4
1 0 0 1 Invalid text mode Invalid text mode
1 0 1 0 Mode 4 Mode 4
1 0 1 1 Invalid text mode Mode 4 (224-line display)
1 1 0 0 Mode 4 Mode 4
1 1 0 1 Invalid text mode Invalid text mode
1 1 1 0 Mode 4 Mode 4 (240-line display)
1 1 1 1 Invalid text mode Mode 4
For the undocumented TMS9918 modes, I used the same naming convention
as in Sean Young's TMS9918 documentation.
To summarize from the above chart, for the SMS 2 and GG VDP only, the M1 and
M3 bits select the display resolution only when M2 is set. If both bits are
set, the regular 192-line display is used. If M2 is cleared, then M3 has no
effect and M1 will select the invalid text mode.
The invalid text mode is identical to TMS9918 text mode. It uses CRAM for
colors instead of using a fixed palette and register #7 for selecting the
text color. Each tile is repeated four times on the display, which limits
the usefulness of this mode. Scrolling only moves the tile graphics
around within their 6x8 cells, the actual position in the name table is not
changed. If bit 7 of register #0 is set, columns 0-23, 32-39 can scroll
vertically while columns 24-31 do not. If bit 6 of register #1 is set,
rows 0 and 1 will not scroll horizontally. Finally, setting the horizontal
scroll to values of 6 or 7 will cause each tile to be filled with the
backdrop color.
If the GameGear is in GG mode, it's resolution is fixed and does not
change when the extended resolutions are used. However, the differences
in sprite and background processing are still used. (e.g. end of sprite
list marker doesn't work, background starts at $0700 offsets, etc.)

Secondo voi li posso utilizzare o abbandono l'esperimento?
grazie a tutti.
