Ua paʻi ʻia ke kumu kumu no ke awa Doom no nā kelepona paʻi ma ka chip Spreadtrum SC6531. ʻO ka hoʻololi ʻana o ka chip Spreadtrum SC6531 e noho ana ma kahi o ka hapalua o ka mākeke no nā kelepona kaomi maʻalahi mai nā hōʻailona Lūkini (ʻo ke koena no MediaTek MT6261, ʻokoʻa nā chips ʻē aʻe).
He aha ka pilikia o ka lawe ʻana:
- ʻAʻole loaʻa nā noi ʻaoʻao ʻekolu ma kēia mau kelepona.
- ʻO ka liʻiliʻi o ka RAM - 4 megabytes wale nō (e helu pinepine nā brand / mea kūʻai aku i kēia me 32MB - akā alakaʻi hewa kēia, ʻoiai megabits, ʻaʻole megabytes).
- ʻO nā palapala i pani ʻia (hiki iā ʻoe ke ʻike i kahi leak o kahi mana mua a me ka hemahema), no laila ua loaʻa ka nui me ka hoʻohana ʻana i ka ʻenekinia.
Hoʻokumu ʻia ka chip ma kahi kaʻina hana ARM926EJ-S me ke alapine o 208 MHz (SC6531E) a i ʻole 312 MHz (SC6531DA), hiki ke hoʻohaʻahaʻa i ka 26 MHz, ARMv5TEJ hoʻolālā kaʻina hana (ʻaʻohe māhele a me kahi wahi lana).
I kēia manawa, ua aʻo ʻia kahi hapa liʻiliʻi o ka chip: USB, pale a me nā kī. No laila, hiki iā ʻoe ke pāʻani wale me kāu kelepona i hoʻopili ʻia i ke kamepiula ma o ke kelepona USB (ua hoʻoili ʻia nā kumuwaiwai no ka pāʻani mai ke kamepiula), a ʻaʻohe kani i ka pāʻani.
Ke holo nei ia ma 6 o 9 mau kelepona i hoʻāʻo ʻia e pili ana i ka chip SC6531. No ka hoʻokomo ʻana i kēia puʻupuʻu i ka mode boot, pono ʻoe e ʻike i ke kī e paʻa ai i ka wā o ka pahu, nā kī no nā hiʻohiʻona i hoʻāʻo ʻia: F+ F256: *, Digma LINX B241: kikowaena, F+ Ezzy 4: 1, Joy's S21: 0, Vertex M115: up , Puʻu C323 : 0.
Ua paʻi ʻia ʻelua wikiō: me kahi hōʻike pāʻani ma ke kelepona a e hoʻomaka ana 4 kelepona hou aku.
PS: Ua paʻi ʻia kekahi mea like ma OpenNet, nā nūhou mai iaʻu, i hoʻoponopono wale ʻia e ka luna hoʻoponopono pūnaewele.
Me ka ʻole o ka laikini, paʻakikī ke haʻi i ka laikini no ke code i loaʻa ma ka ʻenekinia reverse, e noʻonoʻo iā ia he kope kope - kope a hoʻololi, e hoʻololi nā mea ʻē aʻe.
Ua hoʻohana ʻia ka pāʻani Doom e huki i ka nānā, ma ke ʻano he laʻana, makemake wau i ka firmware manuahi no nā kelepona hiʻohiʻona. ʻOi aku ka ikaika o kā lākou chips ma mua o ka mea i hoʻohana ʻia i ka firmware. Eia kekahi, ʻoi aku ka maʻalahi o ka hāmeʻa, ʻaʻole like me nā kelepona ʻike ʻole me nā OS "open" a i ʻole nā mea e ʻae iā ʻoe e holo i kāu code ponoʻī. I kēia manawa ʻaʻole au i ʻike i kekahi e launa pū me, a he mea leʻaleʻa ka hoʻohuli ʻana i ka ʻenekinia. ʻO kahi maikaʻi e hoʻomaka ai, ʻo ia ka ʻimi ʻana i ka hoʻokele kāleka SD a me ka hoʻokele mana i hiki iā ʻoe ke hoʻohana i kēia mau kelepona ma ke ʻano he console pāʻani. Ma kahi o Doom, hiki iā ʻoe ke port i ka emulator NES/SNES.
