NitroGrafx is a PC-Engine/TurboGrafx16 emulator for the DS by FluBBa. Most things from PCEAdvance are ported over and most games run quite good.

Changes:

*Fixed CPU cycles per scanline (455, confirmed on hardware).
*Fixed timing of scroll register writes.
*Fixed Sprite DMA IRQ handling.
*Fixed savestates a bit (should be compatible between versions now).
*Fixed scaling after loading savestate.
*Fixed caching of Bios.
*Better timing of ADPCM playing (still no sound though).
*Debug output now optional, also more info is written.

POWDER is a roguelike game, which is not a port of an existing roguelike. It is built around replayability and long term ergonomics, not short term learning. Author of this piece of software is Jeff Lait.

Changes:

Fireball and Cloudkill always explode at the end of their trajectory.
When you gain permanent intrinsics by evolving or lichifying, relevant temporary intrinsics will be cleared, preventing you from having a silver-tolerant lich. (Nathan Bogue)
Timestamps on the final character dump and the description of how long you lived will now match. (Deozaan)
You can wish for bones and corpses without them instantly dissolving. (Garron)
You can no longer fetch items that have teleport fixed. (Eris Discordia)
When a creature (un)polys into a gargantuan creature, it will now also push away monsters in addition to crushing walls. (Nathan Bogue)
Lich-form creatures that are undead no longer report it being your evil that was useless. (garron Bailey)
When you name an item, the menu defaults to naming the type rather than the specific as this is the usual scenario.
The floor of the kiwi room is now the proper floor tile.
Controled teleport onto the square you are already standing no longer reports that you are blocked, but that you decide to stay put.
Mysterious mapping of rooms fixed. Thanks to Kender and Mental Mouse for tracking this down – it has been annoying me for six years or so! (David Damerell, Eilu, Kender, Mental Mouse)
buildall.sh should work with –use-home-dir again. (garron)
The option menu no longer has Load. Instead it has Quit, which prompts you if you meant this. Loading is now only done from the main menu.
No experience for killing your pets.
Confirmation prompt if starting New Game with active saved game as one can easily accidentally overwrite it.
Some spells when mistargeted no longer waste your mana. Not all, so remain vigilant.
Cancelling your choice in the Wish menu no longer costs a turn.
Fix potential crash when you are killed by splash damage from a thrown item.

While the highscore is kept, save games are never preserved between versions. Please wait until your current character dies before upgrading.

Each player takes it in turns to place an atom on the grid. Players can place additional atoms onto their own atoms.

If too many atoms are place on the same tile the atom goes critical and will explode and place additional atoms. When the atom goes critical it will send additional atoms horizontally and vertically away from it. If this atom lands on a square that has another atom on it, it will add to that atom. Also if the atom is another players it will be taken over by the atom that went critical.

Release notes:

Updated to V0.7

This includes an updated explode calculation that should mean it no longer gets stuck in a loop.
Bars are now shown on the top scree, these give a quick indication on how well each player is doing.
Also some updated artwork.

DSx86 is a PC emulator for Nintendo DS. It’s purpose is to allow you to run old DOS games on your Nintendo DS game console.

Changes:

VGA Mode-X support (Wolfenstein 3D, Fox Ranger). DSx86 now supports all 320-pixel wide Mode-X (and Mode-Y) variations (320×200, 320×240, 320×400, 320×480). In the modes with 400 or more lines the screen is prescaled vertically to 200 or 240 lines, even in ZOOM mode. This is to keep the aspect ratio sensible. If this scaling makes small fonts hard to read, try using screen update mode “Direct”, as that will alternate between odd and even rows to display (a sort of jittering effect).
Mouse support (MJLAPTOP, etc.). You can select whether the D-Pad emulates cursor keys or mouse by toggling the “Mouse”/”Keybd” text on the touchpad. A/B buttons emulate the mouse buttons when in mouse mode.
CGA 640×200 monochrome mode support added (MJLAPTOP).
Key Repeat support (4DOS, etc.). Now when you keep the button (real or virtual) down, it will repeat, like in a real PC keyboard. This is the one change that I am most worried might have broken something.
Bug in “mov reg16,[BP+SI]” and “mov reg16,[BP+DI]” opcodes fixed (WIN).
Bug in “Interrupt Enabled” flag setting after returning from INT2F fixed (Wolfenstein 3D).
Bug in moving data within the EGA VRAM fixed.
Fixed the Brown color in the default EGA palette (KEEN4).
New game-specific “jpe” opcode hack added (CALGAMES).
New game-specific “jpo” opcode hack added (TOUTRUN).
Added “insb” opcode handling (OPENING).
Added all “imul r16, r16, imm16” opcodes (NCMAIN).
Added “imul r16, [di+disp16], imm8” opcodes (UNP2).
Added “imul r16, [idx+disp8], imm16” opcodes (STARTREK).
Added support for input from port 3C2 (FD).
Added support for input from port 3CC (RAIDEN).
Added support for input from port 3D9 (Crazy Cars).
Ignore “Tandy 1000SL/TL – SET UP SOUND MULTIPLEXOR” BIOS call (MIDWNTR).
Support for moving data from EGA VRAM to RAM added (REVENGE, BL, RAMPAGE).
EGA opcode “and es:[di],ax” added (BARD, DK).
EGA opcode “mov byte es:[disp16],imm8” added (KEEN1).
EGA opcode “mov es:[si],ax” added (G).
EGA opcode “and ax,es:[di+disp8]” added (SR).
MCGA Direct mode opcode “mov es:[di],bh” added (CREEPERS).
MCGA Direct mode opcode “mov es:[bx],al” added (MW).
Opcode “aad” handling added (JS3).
Added handling for opcode “repe scasw” when direction=down (STAROPEN, SS, PAL).
Opcode “sar word [bp+disp8],imm8” handling added (RUNVGA).
Added support for teletype text output in EGA mode (ULTIMA).
Added support for teletype text output in MCGA mode (EAGLE).
Added support for “GET ALL PALETTE REGS (VGA)” BIOS call (BASH1).
Added support for “WRITE STRING” BIOS call (RICK2, !STUNTS).
Added support for DOS text output in EGA mode (SIMCITY, SKWEEK).
