The following shows screenshots of particular note.
|
This is Ecco II and is demonstrating horizontal shifting. Every line
is shifted to create a rippling effect. |
|
This is again Ecco II, this time showing what occurs when the emulator
doesn't have a line renderer. The horizontal shifting is approximated
and you end up with blocky movements. |
|
This is the Sonic 1 title screen. Many emulators show Sonic above the
banner instead of 'popping out' of it. The emulation required to do
this involves emulating the hardware limit of the Genesis to only
display a certain number of sprites per scanline. |
|
This is the Sonic 2 title screen. Just like Sonic 1, many emulators
show Sonic and Tails above the banner instead of 'popping out'. This
time the cause is the improper emulation of sprite priorities. |
|
This is the Sonic 1 Marble Zone. This demonstrates the situation
when the priorities as dictated by the LinkData order conflict with the
priority bits contained in the sprites themselves. Note that the high
(layer) priority sprite has been masked by the low (layer) priority
sprite to create a 'cut out' portion of the sprite. |
|
This is the Sonic 1 Marble Zone again, this time with the low priority
layers removed. See also how Sonic's foot has caused part of the grass
to be masked? |
|
This is Wolfchild. Quite a lot of emulators fail to implement
the DMA properly and instead of this nice display the whole screen is
corrupt. As far as I remember, there is actually a bug in Wolfchild,
so it's not surprising emulators get this wrong. |
|
This is the Traveller's Tales logo. Many emulators do not
render this correctly as it uses hilight/shadow features. |
|
This is Columns, inside 3in1 cartridge. Many emulators cannot play
this game beyond the menu screen due to lack of proper controller
support. Another common problem is the score fails to work properly,
due to a quirk of the real 68000. |
|
(png) This is wbug
by Charles MacDonald. It
is a test cartridge
to demonstrate the window bug of the VDP hardware. Notice how the
2345 has become 4545 to the right of the window area
(shown as a grey box). |
|
This is Ecco II 'Sky Tides' stage. This screen uses horizontal and
vertical scrolling plus shadow and hilights. |
|
This is the tcl/tk interface. |
|
This is the console interface (very early version). |
