O projeto foca fortemente na execu\u00e7\u00e3o de aplicativos de jogos e oferece a possibilidade de rodar vers\u00f5es do Windows atrav\u00e9s do Wine e Proton. O c\u00f3digo-fonte do projeto \u00e9 escrito em C e est\u00e1 dispon\u00edvel sob a licen\u00e7a MIT.      <\/p>\n<p>Uma caracter\u00edstica do projeto \u00e9 a aplica\u00e7\u00e3o de um modelo h\u00edbrido de execu\u00e7\u00e3o, onde a emula\u00e7\u00e3o \u00e9 aplicada apenas ao c\u00f3digo de m\u00e1quina do pr\u00f3prio aplicativo e \u00e0s bibliotecas espec\u00edficas. As bibliotecas de sistema padr\u00e3o, incluindo libc, libm, GTK, SDL, Vulkan e OpenGL, s\u00e3o substitu\u00eddas por vers\u00f5es nativas das plataformas-alvo. Assim, as chamadas de biblioteca s\u00e3o executadas sem emula\u00e7\u00e3o, permitindo um aumento significativo de desempenho.       <\/p>\n<p>A emula\u00e7\u00e3o de c\u00f3digo, para a qual n\u00e3o existem substitui\u00e7\u00f5es nativas para a plataforma-alvo, \u00e9 realizada usando a t\u00e9cnica de recompila\u00e7\u00e3o din\u00e2mica (DynaRec), convertendo um conjunto de instru\u00e7\u00f5es de m\u00e1quina em outro. Em compara\u00e7\u00e3o com a interpreta\u00e7\u00e3o de instru\u00e7\u00f5es de m\u00e1quina, a recompila\u00e7\u00e3o din\u00e2mica demonstra um desempenho de 5 a 10 vezes melhor. <a href=\"https:\/\/prohoster.info\/pt\/server\/\"  data-wpil-monitor-id=\"3333\">alto desempenho<\/a>.     <\/p>\n<p>Na nova vers\u00e3o:  <\/p>\n<ul>\n<li class=\"l\"> Foi apresentado um decodificador unificado de prefixos de c\u00f3digo de opera\u00e7\u00f5es (prefix opcode decoder), utilizado no interpretador e em todos os backends de recompila\u00e7\u00e3o din\u00e2mica (DynaRec). O novo decodificador lida de forma mais abrangente com combina\u00e7\u00f5es raras de prefixos de opcode e elimina a necessidade de \"gambiarras\" espec\u00edficas e duplica\u00e7\u00e3o de c\u00f3digo no interpretador e nos backends do DynaRec. A reformula\u00e7\u00e3o do decodificador levou \u00e0 remo\u00e7\u00e3o de c\u00f3digo desnecess\u00e1rio, simplificando a manuten\u00e7\u00e3o da base de c\u00f3digo e permitindo que o DynaRec trabalhe com combina\u00e7\u00f5es at\u00edpicas de prefixos de opcode.\n<li class=\"l\"> Foi iniciada a implementa\u00e7\u00e3o de um mecanismo para remover da mem\u00f3ria blocos de c\u00f3digo convertidos em c\u00f3digo nativo, mas que n\u00e3o est\u00e3o mais em uso. Essa otimiza\u00e7\u00e3o ajuda a reduzir o consumo de mem\u00f3ria ao executar aplicativos que realizam muitas opera\u00e7\u00f5es no in\u00edcio, como Steam e aplicativos que utilizam libcef.\n<li class=\"l\"> Apoio \u00e0 arquitetura ARM64 foi aprimorado: um perfil de build foi implementado para a CPU NVIDIA GB10. No backend de recompila\u00e7\u00e3o din\u00e2mica (DynaRec), a implementa\u00e7\u00e3o de t\u00e9cnicas de otimiza\u00e7\u00e3o de loops continuou, como mover opera\u00e7\u00f5es de atribui\u00e7\u00e3o de registradores XMM\/YMM para fora do corpo do loop.\n<li class=\"l\"> Aumentou a estabilidade e o desempenho do backend de recompila\u00e7\u00e3o din\u00e2mica para a arquitetura RISC-V. O lan\u00e7amento do Steam, Proton e Wine foi garantido, mas para trabalhar com conte\u00fado DRM protegido, que requer emula\u00e7\u00e3o de chamadas de sistema do Windows, exige-se hardware com suporte a espa\u00e7o de endere\u00e7o de 48 bits (SV48) ou o uso de vers\u00f5es modificadas do Wine e Proton.\n<li class=\"l\"> O desenvolvimento do backend para a arquitetura Loongarch avan\u00e7ou significativamente, alcan\u00e7ando a possibilidade de executar Steam, Wine e Proton, mas ainda est\u00e1 atr\u00e1s em funcionalidade do backend para sistemas ARM64. Para funcionamento, \u00e9 necess\u00e1rio utilizar no kernel p\u00e1ginas de mem\u00f3ria com tamanho de 4K (por padr\u00e3o, o Loongarch geralmente \u00e9 definido como 16K). O desempenho j\u00e1 \u00e9 suficiente para executar jogos no CPU Loongarch 3A6000 (2,5 GHz com 4 n\u00facleos f\u00edsicos).      <center>  <div class=\"youtube-placeholder\" data-id=\"6Fa50RHPJcY\" onclick=\"loadVideo(this)\">\r\n        <img decoding=\"async\" src=\"https:\/\/img.youtube.com\/vi\/6Fa50RHPJcY\/hqdefault.jpg\" alt=\"Por que no hosting comum a administra\u00e7\u00e3o do PrestaShop \u00e9 lenta, e no seu n\u00e3o \u00e9?\" loading=\"lazy\" width=\"480\" height=\"360\" style=\"width:100%;height:auto;\">\r\n        <div class=\"play-button\"><\/div>\r\n    <\/div><\/center>\n<li class=\"l\"> A estabilidade do modo Box32, que proporciona suporte a arquivos execut\u00e1veis de 32 bits no Box64, foi aumentada.
