The pen has a dedicated button which was often used to select something +under the pointer icon, much like a mouse button. +However, a few games also had an overlay for the touchpad. + +PicoDrive supports displaying both the storyware pages as well as a pad overlay. +They must be in png format and named like the storyware ROM without the +extension, plus "_.png" for the storyware page , and "_pad.png" for a pad +overlay. Storyware page images should have an aspect ration of 2:1, pad images +should have 4:3. All images can have arbitrary resolution and are automatically +scaled to fit the screen. + +There are 2 menu actions for switching to pages or pad which will automatically +display the images if they are available. To allow for proper pen positioning +there is also an action for having the pen on the page/touchpad or not. Pen +positioning is done through the D-pad if the screen has been switched to either +pages or pad. + + Other important stuff --------------------- @@ -528,8 +555,9 @@ main 68k @ 7.6MHz: yes, Cyclone (on 32 bit ARM CPUs) or FAME/C core VDP: yes, except some quirks and mode 4, not used by games SN76489 PSG: yes, MAME core ADPCM: yes, MAME core -Pico Pen: yes, to some extend -Pico Storyware pages: no +Pico Pen: yes +Pico Storyware pages: yes +Pico pad overlays: yes Problems / limitations diff --git a/platform/libpicofe b/platform/libpicofe index 4563c131..697806c4 160000 --- a/platform/libpicofe +++ b/platform/libpicofe @@ -1 +1 @@ -Subproject commit 4563c13167deb97851397789bf2fb95bb44cf1ed +Subproject commit 697806c41dccf0adb0a3a35171f6eff9a9191240 diff --git a/platform/libretro/libretro.c b/platform/libretro/libretro.c index 6423a61a..62c09103 100644 --- a/platform/libretro/libretro.c +++ b/platform/libretro/libretro.c @@ -1466,7 +1466,7 @@ bool retro_load_game(const struct retro_game_info *info) { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_B, "Red Button" }, { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_A, "Pen Button" }, { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_START, "Pen State" }, - { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_SELECT,"Pen on Storyware" }, + { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_Y, "Pen on Storyware" }, { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_X, "Pen on Pad" }, { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_L, "Previous Page" }, { 0, RETRO_DEVICE_JOYPAD, 0, RETRO_DEVICE_ID_JOYPAD_R, "Next Page" }, -- 2.39.5
